Hello all,

I've finally pulled my truck off the road to do an engine swap and clean it up a bit. I expect that this will be a long project, but I am motivated to get it done and back on the road for next year.

Here's what I have done so far:

I have a fully rebuilt 261 that was bored .060, which was discussed here:
Poncho Rebuild

I pulled the front clip:

I also dropped the driveshaft and removed the propeller shaft from the back of the trans. My next step is to pull the transmission right out as I will clean it up and I have a new gasket set to install in it. Where the propeller shaft goes through the mount that holds it to the frame was pretty loose. I think I will be replacing something here, just not sure what is required yet.

I also found this under the rad mount:

Looks like it had a single mount in the middle at one time. I may already have a replacement piece located to cut/weld in.

So I will try and keep this updated as much as possible. I am hopeful to have more time with the colder weather coming to get out in the garage. Thanks!

Hello Goach2,

It looks like you are installing the 261 in a 1948 Chevrolet Thriftmaster 3/4 ton Chevrolet truck?

What year 261?

What rear-end will you be using?

What clutch assembly will you be using?
Posted By: Goach2 Re: Poncho engine swap - Mon Oct 04 2021 02:41 PM
Hi Martin - I was going to post it there, but I will have many questions along the way and the wording in that forum seemed to suggest it was not the place for that.

Tim - that's right, going in my 3/4 ton. 261 is a 59/60 from a Canadian Pontiac. I just upgraded the rear end to 4.11s and I'm keeping my 6 volt system, with original starter/flywheel and clutch.

I should mention that I'm mechanically inclined, but not a mechanic and this will be a first for me wink

Will you be relocating the water pump (and, using your old water pump)? [chev235guy.blogspot.com]
Posted By: Goach2 Re: Poncho engine swap - Mon Oct 04 2021 04:59 PM
Yes, I had the machine shop install one of Deve's relocation plates so that I can use the original.
Posted By: tclederman Re: Poncho engine swap - Mon Oct 04 2021 05:48 PM
Deve shows/refers-to that plate on his website

However, another member here "invented"/sells that plate,

Go ahead and have the moderator move your build to the Project Journals forum. You can document your build there then ask questions in the appropriate Forum’s. There’s more traffic on those forum’s, so you’ll get more advice as not everybody reads the Journals. That is what I am doing and it work’s great!

Hi Phil,

I'd rather move my previous 'DITY' post to the Project Journals and update that with progress, then use this thread for all the questions I will have along the way.

I'll let the moderators make the call, but my preference would be to get more opinions/guidance and less of the "Not a whole lot of chit chat in here, more like a ride along"...

Bet your excited to get going. I remember when I got mine back from the machine shop, it looked much the same way. It took me a couple of weeks to build it and paint it before I was ready to install it in my truck. All total I removed it in July 2019 and it was back in December 2019. It took me more time to clean everything to get it ready for paint, than it did to do the install. It turned out awesome!

Take your time when you reassemble, check everything twice and you’ll be fine! Good luck with your reassembly!

Good advice, thanks Phil. I agree, just having the front clip off, I can see a lot of work just cleaning up the engine bay before even starting on the engine. I will have to set some parameters to work between or this could go on for quite some time!
Posted By: Goach2 Re: Poncho engine swap - Mon Nov 08 2021 04:46 PM
Ok, this week I am finally pulling the original. Trans is already out and front clip as well. I've read multiple opinions on which bolts to hook to and there doesn't seem to be too much consensus. I'm likely going to use an intake bolt and maybe water pump to pull it, as I don't want to untorque a head bolt. Are there any suggestions though for my freshly painted block? The intake/exhaust and water pump are also off of it...
Posted By: klhansen Re: Poncho engine swap - Mon Nov 08 2021 04:56 PM
When I pulled mine (with tranny still mounted, but with the body off), I hooked to the generator bracket on the front left and a starter linkage bolt on the bell housing on the right. It was not very well balanced and I used a ratchet strap hooked to the clutch linkage. You may be able to use the starter linkage bolts on both sides, and a thermostat housing bolt on the front. Even without the tranny it's going to be a bit heavy at the rear.
But if you want to avoid paint chips, then head bolts would be best. There's no worry about removing two of them, as they can be retorqued without issue. You just have to figure out which two to use for best balance. The shop manual says which ones, but that's with the tranny still attached.

On my GMC engine, I used the valve cover bolts on a spreader bar I made, that way it will remain upright and it can be tilted for insertion.

Knew I had a better picture.

Buy a couple of 3/8-16 Grade 5 (NOT all thread) bolts slightly longer than the rocker arm stand bolts and make a couple of short pieces of angle iron with holes to bolt the lift chain onto.

Vice grips.
Posted By: Goach2 Re: Poncho engine swap - Wed Nov 10 2021 02:20 AM
If I make it worse, how does one go about replacing this? A whole new line? Or can a new end be put on it?
Posted By: 37 GC Re: Poncho engine swap - Wed Nov 10 2021 02:44 AM
a good set of line wrenches come in handy on brake lines, oil filter lines etc.
Posted By: EdPruss Re: Poncho engine swap - Wed Nov 10 2021 03:39 AM
Tubing wrench slips over line and move to nut, come in sizes. Looks like it is too late for the smaller nut, can you get the other end loose, then undo the large nut, otherwise cut the line to get it loose.

Ed
Posted By: Goach2 Re: Poncho engine swap - Wed Nov 10 2021 04:57 AM
Is this the oil pressure gauge? Would I be able to reflange it? Pretty small line. I have line wrenches, but it's too rounded.

Can't tell from your picture. Where does the other end go? If it's also a similar fitting, you can replace the whole thing. All the fittings and tubing would be available at a hardware store.
Like I suggested, vice grips will get the fitting loose, or grind it completely down. I'd be surprised if vice grips won't get that loose.
Posted By: Goach2 Re: Poncho engine swap - Wed Nov 10 2021 12:26 PM
It goes through the firewall, under the dash
Posted By: Goach2 Re: Poncho engine swap - Wed Nov 10 2021 12:49 PM
Actually, this is on the block, under the manifolds. If it's the oil pressure sensor and I'm going from a 216 to a 261, do I need a higher pressure sensor?
Posted By: walterhvogel Re: Poncho engine swap - Wed Nov 10 2021 06:20 PM
I used an aftermarket oil pressure gauge that came with plastic tubing and compression fittings. The plastic tube with compression fittings worked for many years.
Posted By: klhansen Re: Poncho engine swap - Wed Nov 10 2021 08:01 PM
If that's the oil pressure gauge line, then no problem cutting it and removing the fitting from the block. Going from a 216 to 261, you probably need a higher range gauge. There's no "sensor", but just the pressure gauge that reacts to the oil pressure transmitted up the tube. Most modern gauges are electronic, but the old ones directly measure the pressure from oil sent to the gauge. If the line breaks, oil will be pumped out the break, wherever it occurs, in the engine compartment or behind the dash, so you need to be careful on routing so the tube doesn't rub on anything that might wear thru it. You should also put a vibration loop in the tube if you use copper so it doesn't break from vibration. Walter's suggestion of plastic tubing alleviates the vibration problem. It needs to be rated for the pressure expected (probably 100 psi minimum).
Posted By: Goach2 Re: Poncho engine swap - Wed Nov 10 2021 09:18 PM
So, if I cut this line, can I reflange it? It's so small!
Posted By: klhansen Re: Poncho engine swap - Wed Nov 10 2021 09:48 PM

It's probably not a flanged line, but a compression fitting, either a separate ferrule or a captive ferrule fitting like this. [mcmaster.com]. Cut the tube straight across near the fitting and it should just re-insert into a new adapter fitting that you'll screw into the block.

Vice grip for the win! Everything has been detached from the engine, tomorrow she comes out.
Posted By: EdPruss Re: Poncho engine swap - Thu Nov 11 2021 02:41 PM
Normally there is a small washer with an .032” hole in it to prevent all the oil rushing out fast, might already be in the system, usually under the initial fitting in the block.

That would act as a snubber so the gauge doesn't bounce with any pulsations in oil pressure from the pump. I didn't look to see if there was that small hole in the fitting on mine, but will try to remember when I start putting it back together.

Ok, now that the engine is out, time to start transferring parts to the new one. Since I am keeping the 6v system, I will be keeping the starter, generator, coil, flywheel and bell housing. I have the adapter plate already installed, so I will also take the waterpump, pulley and fan as well as the balancer. Front mount plate was also installed, so I will reuse the front mount, but replace the rubber and bolts.

Anything else?

I would go for a new clutch kit for the trouble of having to do the work to change it down the road but that is just me .I do see a broken spring in the disc and some slippage marks but that is why I would change it if it were mine because I dont know too much about how they wear ,I would also change the real ease bearing and pilot bearing .
Posted By: klhansen Re: Poncho engine swap - Sat Nov 13 2021 01:23 AM
Get the flywheel resurfaced as well. Might as well start off with reconditioned parts since you have it down that far.
Posted By: Goach2 Re: Poncho engine swap - Sat Nov 13 2021 02:24 AM
Resurface flywheel, change out clutch, pilot and release bearing.

Get a bronze pilot bearing, not a steel one.

What do I measure to determine the size of the clutch? Seems to be two sizes, 9-1/8" and 10".

Got it off and cleaning it up. Does it just tap on? Does it need any product to keep it on place?

Still trying to determine the size of this clutch too.

Posted By: klhansen Re: Poncho engine swap - Sat Nov 13 2021 10:11 PM
I believe clutch size is based on the diameter of the disk. I just measured mine and it's ~9". The pressure plate diameter is ~9.5".

The balancer just drives on. Use something to support the rear of the crankshaft and a piece of hardwood and a large hammer. You'll feel/hear it when it's home. Put some sealant in the key slot so that doesn't leak (probably overkill, but since you already have it off, it can't hurt.) There's nothing but friction keeping it in place. Later engines used a bolt in the center of the crank.
Posted By: Goach2 Re: Poncho engine swap - Sun Nov 14 2021 01:50 AM
I am clutch illiterate, so I'll put this here for confirmation on the size I need:

That would be a 10" or 11" clutch. I had forgotten you were working on a 261. My engine is a 216, so not the same.
If you know the year of the Engine, NAPA or other parts store can probably fix you up with a clutch kit.
Posted By: Goach2 Re: Poncho engine swap - Sun Nov 14 2021 02:25 AM
This was the clutch that came off the 216, with the 4 speed.
Posted By: 55shaker Re: Poncho engine swap - Sun Nov 14 2021 02:33 AM
Looks like a 10.5 inch to me.

It would be for a 3/4 ton or heavier truck. They came with a 10-3/4 inch clutch.
1/2 ton models would have a 9-1/8 inch clutch.
[on edit]After a bit more research I found the 10-3/4 ton clutch was available as an option on 1/2 ton trucks. The smaller clutch has 6 bolts holding it on to the flywheel, while the heavier duty clutch (and flywheel) has 9 bolt.

Finding a HD clutch seems to be a bit difficult. If I can find a new disc, is reusing the pressure plate a bad thing?
Posted By: klhansen Re: Poncho engine swap - Mon Nov 15 2021 10:12 PM
If the surface where the disc runs on the pressure plate is in good shape (no heat cracks or discoloration or deep grooves), and the spring is in good shape, then it should work OK.
Posted By: KEVINSKI Re: Poncho engine swap - Mon Nov 15 2021 11:14 PM
I would take it down to a local brake and clutch shop so they can see it ,they may have it in stock ,If you are in Ontario near the border you may be able to order from state side and pick it up Napa in the US is usually a lot cheaper than on our side it is disappointing looking at the difference in prices for the same part numbers.

Looks pretty good. I've done similar weld buildup on my front crossmember, as well as a somewhat less severe crack on the engine mount crossmember.

I would grind a bit to widen that crack to form a "V" before welding. You want to be sure to get full penetration.

Sorry, probably posting too much, but it was suggested to do this before the engine goes in, so I just wanted to post a follow-up. I have engine parts arriving today so the specific questions are coming!

What kind of welder, and welding rod are you using? Try some 7014 next time, especially if you're using an AC buzz box.

Front mount cover has been cut out. Is this going to be a problem? Is it worth welding a piece back in?

The filling station has them 10.95 .it is a grease shield so as long as it stops the grease from getting to the rubber you could use it.on second thought looks like it is a big hole weld or replace.
Posted By: klhansen Re: 1948 Thriftmaster 3/4 ton - Poncho engine swap - Sat Nov 27 2021 10:22 PM
It may have just been worn thru. Mine was in similar shape but not quite as bad as yours. I bought the replacement from The Filling Station.

Does the front mount 'cover plate' always have these impressions?

Also, does the curved edge face the engine or the rad?

The shop manual doesn't cover that. Install it so there's the most clearance to both the oil pan and the radiator. I don't recall how I did mine, but could go look at the engine (I have it on a stand with the front mount bolted to the front plate of the engine.)
It does tell you to be sure there's clearance between the cover plate you bought and the lower plate. If there's interference, the rubber mounting won't work to absorb vibration.

Thanks, plate looks pretty flat, might build mine up or pick up another. Still unsure about the lip.
Posted By: klhansen Re: 1948 Thriftmaster 3/4 ton - Poncho engine swap - Sun Nov 28 2021 10:23 PM
I didn't pay close enough attention when I took mine off. I put it on with the curved part facing forward, but after looking at it, that puts the drip cover pretty close to the crank pulley. I may have to do some more research and maybe turn it around to see if it's a better fit. It won't interfere with the radiator the way it is now.

Your mount plate looks pretty worn. Likely from vibrations and loose fasteners over the years. The spots where the carriage bolts go thru are worn where the heads sit. I had to weld on the front engine plate to get the square holes square again, but the mount parts other than the drip cover were OK.

You can get the whole mount set from the usual vendors.

It looks like the side cover if it is it should be okay to turn it tite a bit if it is. The steering boxes are famous for leaking and most use cornhead grease instead of the gear lube.it would not hurt to take the plug on the top out and look inside to see if there is any fluid in there.

So I'm running out of time before I have to get the hoist back to the owner. I haven't found a decent clutch kit yet and will likely have to get the engine in place before I do. How hard is it to put a clutch in with the engine in place? Assuming I should get the flywheel machined and installed first?

It really doesn't matter whether the engine is installed or not, as you have to install the flywheel and clutch AFTER the bell housing is bolted on. Inspect the flywheel to see if it needs to be machined.

I'm wondering if it's worth trying to find this elusive 10-3/4" clutch kit. Local place will do a clutch and plate rebuild for $500, but the smaller clutch kits are way less. Would it be easier for me to just find a 6v flywheel with 6-bolts? Not like I will be hauling cattle in it...
Posted By: KEVINSKI Re: 1948 Thriftmaster 3/4 ton - Poncho engine swap - Tue Dec 07 2021 10:06 PM
Have you tried Napa I found this but you would have to check as it looks like you have the heavy duty clutch.It may be worth it to go down to one of the older brake and clutch shops with your assembly to show them and see what they think

Local place will rebuild it for $500. Not sure if this is the norm, but it wasn't in the original budget 😒
Posted By: klhansen Re: 1948 Thriftmaster 3/4 ton - Poncho engine swap - Wed Dec 08 2021 12:34 AM
If the local place will check the pressure plate for way less than that, and find it good, you could just replace the disk (NAPA also lists that).
But for less than $200 a complete kit from NAPA is the way to go.
Posted By: Goach2 Re: 1948 Thriftmaster 3/4 ton - Poncho engine swap - Wed Dec 08 2021 02:04 AM
Napa doesn't seem to ship over the border and NAPA Canada does not have this clutch.

Posted By: KEVINSKI Re: 1948 Thriftmaster 3/4 ton - Poncho engine swap - Wed Dec 08 2021 03:46 AM
When I did mine I was told to machine the flywheel ( I don’t think it cost much it was like machining brake drums or rotors it has a stamp on it indicating the minimum thickness I think ) I would clean it up by hand with some emery cloth and see how it looks you would be able to see better if it has hardened spots or other imperfections from the clutch spinning and heating it up if it cleans up good I personally would leave it but I am no pro .Let’s see what others think
Posted By: klhansen Re: 1948 Thriftmaster 3/4 ton - Poncho engine swap - Wed Dec 08 2021 04:22 AM
I just had my flywheel for 9" clutch resurfaced. Cost me $95 US (Alaska prices). I probably could have cleaned it up with some emery cloth, but it was kind of rusty and pitted. I agree with Kevinski. Clean the flywheel and look for hardened spots, cracks or deep gouges. If you find those, get it resurfaced.

Next get the 216 balancer painted and installed - just line and rubber mallet?

Install bell housing - antiseize on bolts?

Motor mounts installed on engine and bell.

Install engine. Flywheel at machine shop now and still looking for a clutch.

Am I missing anything?

I'm using Permatex High Strength Red Gel currently. I was using Loctite 680, but that's because is was needed for a specific application.
But the only time you really might need high strength is for critical applications (driveshaft u-bolts, etc.)
Blue is probably fine for the bell housing and most other fasteners.

That's the block drain for coolant. You can either use the petcock shown in your pic or a pipe plug (do NOT use a bolt, as it won't seal well in the tapered threads in the block and may damage them.)

Posted By: klhansen Re: 1948 Thriftmaster 3/4 ton - Poncho engine swap - Sat Dec 11 2021 06:37 PM
If the bolts are the right size and length, they should JUST go in with the timing cover in place. The attached photo was the solution a PO used on my truck - not recommended. I bought 7/16 Carriage Bolts. Made sure the square openings were the right size (may have had to relieve one just a touch) and I believe I had to cut the bolts to the right length. Also drilled them for cotter pins for the castle nuts. I believe the originals were fine thread, but I bought coarse thread, the only thing I could find - Link [amazon.com]

So this front cover has a threaded block right in the middle. I had to shorten the bolt shoulder on each one and ream out one hole slightly, but both bolts dropped in place:

Looks like you might need to check the fit of those two bolts in the sleeves in the engine mount pad. I would probably tack weld the bolt heads in place so they don't turn. The bolts heads should probably be all the way down on the front engine plate, not up where that block is. No idea why that threaded block is there. Maybe a modification someone did along the way to run the bolts up from the bottom. I went the other direction, mounting the entire engine mount assembly to the the engine. I think it'll be easier to stab the bolts into the frame holes instead of hitting the sleeves when lowering the engine in place.

On my truck, the ground strap was on top of the frame like you have it shown. But put the bolt in from the top and the nut on the bottom. That way, if by chance the nut comes off, at least gravity will keep the bolt in place and the strap won't fall off. Also, that same bolt holds a clamp for the positive cable going to the starter. As far as keeping the strap shiny, I sure don't know of anything. I think they're available tin plated, which holds off discoloration for a while. There's a picture in THIS POST of when I was disassembling my truck.

You will have to take the paint off the frame we’re the strap goes for a good contact put a little grease between the two so it won’t corrode

Ya, will clean the frame and put some anti-ox on the wire connections.

For the fuel pump, I put it on and traced it then took it of and wheeled the paint off. Do I need some permatex on the gasket? Blue locker on the bolts? What can I put on the fuel body to keep it clean looking? Does fluid film dry?

I don’t think fluid film drys ,there are lock washers on the bolts for the pump but a dab blue thread locker would not hurt. A gasket is necessary for the pump and whatever your preference to use with it or be it dry up to you .

I'm not sure it's really necessary to remove the paint where the fuel pump goes. There's no need for it to be grounded to the block. I don't think I'll even bother removing the paint where the manifolds bolt up. The paint will serve as gasket sealer to my mind. I think it's too much trouble to remove the paint, especially at the manifold mounting surfaces. I know If I did do that, there would be bare spots where I "colored outside the lines" with a wire wheel that would be susceptible to rust.

I have always cleaned off the surfaces then put on silicone or aviation gasket shellac with the paper gaskets . On the cork gaskets I have used a little bit of white grease . I am always concerned about leaks and have took my time to have everything clean and tightened up evenly but it is always frustrating when you do all that work and it leaks but that’s the way it goes at least for me.

I picked up some Ultra Grey for assembly, was planning on doing a light smear on both sides of the gasket. Hope that will work.

Also, petcock wouldn't come out of the old block, so I'm likely just going to keep the plug in it. Probably not something I will ever use...

While in there with the drain petcock, many years of dirt can clog the drain, get a stiff wire and when you can get water in the block, clean it out so it drains well. Big blocks have 2 drain plugs.

Posted By: KEVINSKI Re: 1948 Thriftmaster 3/4 ton - Poncho engine swap - Wed Dec 15 2021 09:32 PM
Take the plug out and check if it is plugged you can take a wire and wiggle it in and around there and make sure it is clean .once you are satisfied it is clean you may want to flush out with water as I think you said you have a new rad .they may have cleaned the block when it was rebuilt.After you are satisfied it is clean I don’t think you would use the petcock for while anyway and all it does is make it easier to open up to drain the block. I would also be careful taking the plug out as not to damage the threads and the block.

So here's why I have for flywheel bolts; far right off 216, rough, looks like they've been reused before. Middle off a 235, little mangled, but probably useable. Left, bolts with star washers off 261.

Thoughts?

The bolts with the 2-bolt keepers get buggered up because the bent up tabs on the keepers prevent the socket from seating fully on the bolt head. But any of them are probably fine to use.
Your keepers look about like mine did. But they at least had an intact corner to bend up to keep the bolt from backing out. But the locktite is the first line of defense against that happening.

Whatever holds the flywheel in place. I'm not a fan of star washers. Modern flywheel bolts (as in my 7.3L diesel) use no lock washers, just a flat ring under all the bolts.

So, looking at installing the water pump, but need the generator bracket installed at the same time. The 261 came with the top bracket and the 216 the bottom:

[img]https://www.stovebolt.com/ubbthread...umber/37846/filename/20211217_104044.jpg[/img]

I'm assuming with relocating the water pump, I will want to use the 216 bracket. Will the slight difference in the bottom mounts affect the belt size?

Locktite is probably not needed. Rust molecules will perform that function. I think the exhaust heat will destroy the locktite anyway.

Looks to me like the generator needs to move back a bit. You can see the back edge of the crank pulley (red arrow). Unless the generator mount bolts are a sloppy fit and it's not aligned straight with the crankshaft axis.
Also looks like you should have repaired the radiator mount point as well (yellow arrow). There should be two distinct holes there. Looks like it has broken out over the years.

Bolts were all loose, but I will keep an eye on that when I do final assembly. I'm waiting on a rad support as mine was broken. I will fix the cross-member when I have the proper holes to align.

For these gaskets, they don't line up all that great, should I be trying them back, out of the port? If so, what would be best to do this? Steel reinforced gaskets...

You may have to take the manifolds and get them resurfaced so they're flat across the ports. Check with a straightedge (carpenter's square, etc.) Do you have the intake to exhaust bolts torqued? If so, you should loosen them and try again. They should be tightened after the manifold to head bolts are snugged up.

If you mean the manifold to block bolts, you can use an extension on a torque wrench.

Posted By: klhansen Re: 1948 Thriftmaster 3/4 ton - Poncho engine swap - Thu Dec 23 2021 04:49 AM
As long as the angle isn't too far off straight, a swivel socket will work. I just checked my manifolds and I see that the intake is in the way of a straight extension. You could use a box wrench and judge the torque by comparing with the other bolts. Or use a spring scale on the end of the wrench. The spec for the center clamp bolts is 15-20 ft-lbs, so 15-20 lb of force on a foot long box wrench would be correct. Or 30-40 lb on a 6-inch long wrench.

If you got to torches you can heat pipe cherry red and if it only needs a little bend it will bend just have to be careful not to kink.you could put the pipe on manifold heat then pull the pipe up or down depending on we’re you need to bend it ..that is of course if it is unattached to the rest of the system at the back.

We’re your finger is on your picture it looks like the bolt hole was plugged, maybe scrape some paint away to see what is plugging the hole could just be crud under the paint unless someone had a reason to fill the hole .here is a picture of a block from the net and it has the same cast with the threaded hole.

That forward hole on the 216 goes into the water jacket, so you should be able to drill and tap there, if there isn't a hole. The boss toward the rear by the freeze plug isn't drilled and tapped on my 216. But whether the linkage will work in either hole depends on the length of the lever arms and the shape of the rods.
Posted By: Goach2 Re: 1948 Thriftmaster 3/4 ton - Poncho engine swap - Wed Dec 29 2021 01:32 AM
Maybe the Canadian block is different. It doesn't have the oil bypass pin either. I'll probably end up modifying the pedal rod. I would have to drill and tap behind the manifold.
Posted By: Goach2 Re: 1948 Thriftmaster 3/4 ton - Poncho engine swap - Wed Dec 29 2021 03:42 PM
Ok, I have room to get a bit in there to drill and tap the block. Can anyone suggest the size to drill/tap it to?

Also, the 216 has a longer pin that pushes the butterfly out away from the block, but the one off the 261 is shorter. Do I need the longer one?

Do you have the Rochester carb ,my 54 with a newer 235 has the throttle linkage by the frost plug .I have a spare 235 engine also 1958 era and it has the throttle pin still in it but it is in the hole that is plugged on yours .my linkage on mine goes straight up and lines up with the carb.I know the older trucks had a different cone t to the gas peddle.
Posted By: Goach2 Re: 1948 Thriftmaster 3/4 ton - Poncho engine swap - Wed Dec 29 2021 05:22 PM
The linkage that came with the 261 works fine, except that the pedal rod is too long. I think a tap is best, as I won't have to modify the original linkage at all.

Posted By: KEVINSKI Re: 1948 Thriftmaster 3/4 ton - Poncho engine swap - Wed Dec 29 2021 06:31 PM
I did nothing to my peddle rod .I think there is a difference between the older ones but I think it is just at we’re it attaches to the peddle . I will double check to see if anything looks modified on mine and maybe see if I can measure the length.
Posted By: KEVINSKI Re: 1948 Thriftmaster 3/4 ton - Poncho engine swap - Wed Dec 29 2021 07:04 PM
Took a few more pictures ,didn’t measure but the engines would be sitting in the same spot .if you need I could take it apart to measure the rod but it’s chilly today . Don’t see any mods to any of the parts. The peddle in the cab is high because it is not connected to the carb so when it is connected the peddle is lower.

The dip stick and draft tube are pressed on and if I remember correctly I put a dab of aviation gasket on mine .the draft tube should also have a bracket with a bolt to hold it in . Your distributer should have the advance that clamps onto it and I think it has a o ring but not 100 percent on this one maybe someone else will verify
Posted By: Goach2 Re: 1948 Thriftmaster 3/4 ton - Poncho engine swap - Thu Dec 30 2021 12:47 AM
Should dip stick tube have some kind of stopper ring? It's totally straight, nothing to 'seat'.
Posted By: KEVINSKI Re: 1948 Thriftmaster 3/4 ton - Poncho engine swap - Thu Dec 30 2021 01:39 AM
I don’t think there is any stop for the dip stick tube I think it will only go in so far my guess 1/2 inch I also don’t think I here is a o ring for the distributer I looked a my spare and doesn’t look like there is anything .

I don’t have those on mine maybe for vacuumed advance line . There are some links in here about the distributer and I don’t think there was any gasket or o ring as it can hinder movement of the distributors vacuums advance and you would want to be careful that the distributer goes all the way in as it drives the oil pump .

Okay thanks.In regards to your oil filter I would find out some more imfo about your 261 ,is that the filter that came with the motor , some of the engines had a pin that made a difference for the type of oil filter ,I am confused at yours as does not look like it has the pin so just guessing that maybe your motor is a lot newer but either way I would look into it and make shure there is going to be enough oil flowing when you start it up .
Posted By: Goach2 Re: 1948 Thriftmaster 3/4 ton - Poncho engine swap - Thu Dec 30 2021 08:18 PM
This one came out of a '60 Pontiac, so the air cleaner hung down low in the front of the manifold. That's why the lines don't fit, I need to move it back where it belongs...

I see mine looks the same but the bracket is welded in a different spot .The filter housing is thick metal may be able to grind off bracket and rotate the filter then re weld ,but that would mess up your nice paint . Curious does inside your filter have a spring or spacer.

Yes a filter would be beneficial some use two one under the floor near were the tank line comes out and one before the carb but after the fuel pump.you should check for dirt and rust in the tank before installing the new line and whatever else you decide.

I have use this before my carb and ordered a few of these as they were cheap and use the basic filter inside that can be replaced .the replacement filters are readily available fairly cheep.You have to make shure you get the right line size.you could go to Canadian tire with the size and match it up i have done this before and found some of the throw away ones are quite pricy.my truck has not been run in 5 years so can’t tell how well they worked.hopefully in spring.

I think you have too many joints in there. It's hanging out there quite a ways. Can you remove the two fittings your index finger is pointing at and put the brass nipple directly in the tee? Both should be tapered threads and should seal nicely when snugged up.

I changed the position of the oil pressure sensor fitting and the line to the oil filter. Any issues doing it this way? Or is it too much force on the sensor? This way better avoids the exhaust.

I don't think that the dipstick should touch the bottom of the pan. It might eventually wear a hole there with enough vibration. Maybe someone will measure their dipstick and tube in relation to the block for you.

That type of fitting is a captive ferrule type. You shouldn't need to do anything to the end of the tube. I would carefully ream the end of the tube to remove any burrs from cutting the tube.

Going to plumb it in next to the carb. One question I have is in regards to the oil filter. The support rod from the firewall to the fender passes right overhead. Has anyone had any issues pulling their filter out? I'm wondering if it will clear it once the fenders are reinstalled...

Mine is close but not overhead, does your oil filter have anything inside besides the filter like a spring or spacer .

Ok, looks like the support rods will widen out once the fenders are back on. No springs or spacers in my filter, hopefully nothing is missing!

Mine does not have any either it is a Canadian filter that is why I asked not much imfo on the net for them.

Kevinski - old filter is 5" tall and 4.25" in diameter.

Saw a guy on youtube use a vise to pinch the stainless to flare it, going to try that.

Also got around to welding the deep groove up:

For the shaft:
1 - do I need to disassemble it any further?
2 - how much of it can I paint? Can I do the ball joint on the end? Or just leave it oiled?

I would put the splices in the vertical since your new bottom piece looks to be pretty solid. You could use the bolt hole locations on the original to insure that the bottom piece is installed in the right place. You could use a couple of pieces of the original as fishplates for the joints. That would help line them up properly as well.

How does the compression fitting work? It's pretty loose on there, just keep it close to the screw cap and it should push/squeeze it in place?

I just ordered some C4P oil filters and I have a few questions:

- How much oil will I now need for the 261?
- Am I able to put the oil in and add a filter later? Is this a bad idea?
- Since this is first start of a newly refreshed engine, how soon after should I be changing out the filter?

Looking forward to first start smile

Canadian tire stocks the filter,there product number is on the picture I posted above a few posts ago ., no problem taking the top off the filter cover but I usually put some oil in the canister when I change the oil as well as use a turkey baster to get the old oil out when I change the oil.

Ya, looks like substantial storm headed this way.

So I got plugs cleaned up and gapped, same with the points. Oil filter came in too, so ready to pour that in. Sounds like 7 quarts is right, based on other posts. I can't trust the dipstick yet, as I had to add one since it was missing and it's possible something is off. I'll put in 7 and we'll see what she looks like.
Posted By: Goach2 Re: 1948 Thriftmaster 3/4 ton - Poncho engine swap - Sat Jan 15 2022 08:39 PM
Being a Pontiac engine, looks like 5 quarts is what it actually holds. I just put in T liters, hope that's ok!

Yea was just going to say but before I posted I found this on the Pontiac form . That way you can check your dipstick after the proper amount of oil is put in as it may be the same as one of your old motors but it I think it also depends if the oil pan is the same .

Tripped up by a bad charger. In the meantime, clutch and pressure plate installed. Also did the 'cold' valve adjustment from the manual. Hopefully soon it'll fire. Then on to the transmission...
Posted By: Goach2 Re: 1948 Thriftmaster 3/4 ton - Poncho engine swap - Wed Jan 19 2022 01:23 AM
Ok, I have spark and gas, but it's not firing. It was firing every 5 or 6 revs but that was it. I bolted down the distributor with advance at zero degrees and rechecked the cold valve lash. Now it doesn't pop at all. Plugs don't seem to smell like gas and if I open the throttle, there is a puddle of fuel in the intake. Suggestions?
Posted By: KEVINSKI Re: 1948 Thriftmaster 3/4 ton - Poncho engine swap - Wed Jan 19 2022 03:58 AM
Have you favourite beverage start from square one and check and rule out one thing at a time until you find what it is .I remember putting my engine in years ago and I had my distributer 180 degrees out it would still line up with the timing and it would fire .That is my guess
Posted By: WICruiser Re: 1948 Thriftmaster 3/4 ton - Poncho engine swap - Wed Jan 19 2022 12:57 PM
As Kevinski said go back to the basics, compression, fuel, and spark. It sounds like you have conformed fuel in the intake and we gather that you have compression so spark, at the correct time would appear to be the missing ingredient. Easiest check for timing being close is to put the engine at TDC on the compression stroke (both valves closed) remove the distributor cap and see if the rotor is pointing toward the number 1 spark plug wire. If it's in the neighborhood timing should be good enough to fire, or at least pop. If timing looks good and you know you have spark then try a quick shot of starting fluid in the intake. If it pops on the starting fluid you don't have sufficient fuel.
Posted By: Goach2 Re: 1948 Thriftmaster 3/4 ton - Poncho engine swap - Wed Jan 19 2022 01:26 PM
Ok, first thing's first. Is the distributor supposed to sit lower than this? I asked earlier and didn't get a response. Should it sit right on the vac ring on the block?

I would need to go look at my engine but I believe the flange should be tight to the block, as shown in the picture the mounting bolt would bend the flange as you try to tighten it.
Posted By: Goach2 Re: 1948 Thriftmaster 3/4 ton - Poncho engine swap - Wed Jan 19 2022 01:52 PM
I already had the flange bolted down, it just slides up and down the shaft, no bending. Maybe it's not in the oil pump...
Posted By: KEVINSKI Re: 1948 Thriftmaster 3/4 ton - Poncho engine swap - Wed Jan 19 2022 02:08 PM
I don’t think it should slide up and down that much it should allow for the distributer to turn but not go up and down .I think mine has a clamp on the advance but I see others don’t but maybe you the vacume advance is not on the distributer proper. I will check mine a little later . When you put the distributer in you can look down in the engine and see the slot for the oil pump and turn it to line up when you put the distributer in .(by the way did you prime the oil pump).

Looking at your picture then mine it looks like your vacume advance is clamped to far up .I would use a piece of coat hanger cut and bent straight then use it to measure how far it goes down in the engine in the oil pump slot then compare that measurement to the distributer .here is a Picture from Deves site.

Spun the oil pump until it seeped out the rockers. Last one took a bit before it dribbled out. Didn't have the filter canister tightened down so a nice oil mess.

I have the flywheel on the ball-bearing with Poston at the top, but how do you tell if the valves are closed? They all look the same to me...

Put you thumb over the empty #1 spark plug hole. Bump the starter over until you feel the upstroke of the piston force your thumb out. Now your on TDC of the compression stroke on #1 cylinder. Wire from there.

You can also check by the timing mark on its mark,rotor on distributer pointing to fire on number one cylinder and the number one valves both closed ,no rockers pushing down on the valves.

Problem with a new build is you might not get the distributor in right to mark location. Tonight I rolled it to TDC and set the distributor back in it. Also adjusted all the valves again. I was right with the position of the distributor after all. I could feel when it was hitting the top of the pump, versus when it went down the extra 1/4" or so. Buttoned it all up again and hit the starter. I got a few pops, but the battery seemed to be low. I put a 12v jump on it and gave the distributor a slight twist and it took off right away. Only ran as long as it took me to walk around it and turn it off. I have to get the exhaust rebent to fit the new manifold, so it's super loud. Very gratifying to hear it run. This weekend I will open the doors and do a quick timing adjustment. I still have to get my rad back from the shop, so won't be running it for very long.

Since rad is next, I'm working to patch the cross member where it was worn right through. Got some welding and drilling to do...

Seeing that it a fresh build if your not planning on it already , it might need a proper break in period along with some break in additive .

Machine shop said run 20 minutes at 2000 rpm. That was about it. Any additional advice is appreciated!
Do not start it and shut it down repeatedly. Wait until it’s ready, radiator full. Fresh supply of gas. Then do your 20 minutes @ 2000. Starting and stopping is not good for the cam.
Posted By: WICruiser Re: 1948 Thriftmaster 3/4 ton - Poncho engine swap - Fri Jan 21 2022 12:56 PM
As Justhorsenround said, it is critical to avoid start ups and low rpm operation. I would treat the 2000 rpm number as a minimum as you want to keep the cam lobes lubricated for the break-in period. A break-in oil additive is a good idea as engine oils these days tend to be formulated for modern engines that do not have the same cam break-in concerns.

Ok, I need to figure out the oil situation first then. I have a Pontiac manual, which states that it need 4 qts and 1 more for the filter. I put 5L in, which is like 5.2qts. The engine came with a dipstick and tube, which wasn't installed, but I was told is the original. I replaced the tube with one almost of identical length, using Deve's instructions. 5L takes me to the 'Low Oil' mark on the stick. From bottom of washer to tip, it's 15-3/4" long, 14" to the 'Full' mark. The tube is about 8.1" long and sits 7-3/8" from block to tip. The way it sits, it feels like it needs one more quart, but I'm concerned about over filling it. This engine is out of a Pontiac, and I have the letter from GM stating that. Perhaps someone put a truck pan on it at one time?
Posted By: Goach2 Re: 1948 Thriftmaster 3/4 ton - Poncho engine swap - Fri Jan 21 2022 07:00 PM
I'm going to take some measurements of the oil pan and compare to another that I have from a truck (they look the same). If it comes out the same, does that mean that they both have the same capacity? From what I've read, trucks with 235/261 typically use 6qt with a filter...
Posted By: Goach2 Re: 1948 Thriftmaster 3/4 ton - Poncho engine swap - Sat Jan 22 2022 12:24 AM
I have this pan out of a truck and the deepest part of the pan (approx 9"x9"x7") is actually a bit smaller than the one on the new engine. Not sure if that speaks to amount of oil?

Is the oil pan the one that was on the engine when you got it .one of the posts I read says the oil pan has to match the oil pickup.

This is the pan that was on the engine when I got it and I have to assume it's original.

I think this one best describes the dipstick, as I measure about 14" to full line:

58-59
ALL (6 cyl.) exc. Ser. (3C-3D-3F)
13 13/16" under washer to full line
14 13/32" under washer to add line

Ok, moved the oil discussion to here: https://www.stovebolt.com/ubbthreads/ubbthreads.php/topics/1438297.html#Post1438297

Going to move on and changed out the front bearing in the transmission.

Just to confirm, I have decent looking synchro's for first gear, but they aren't brass. I was told to just leave these in place since 1st is rarely used:

If you're talking about the sawtooth pattern between the gear clutch teeth and the synchronizer, I believe that's normal. Everything else looks good to me.
Posted By: Goach2 Re: 1948 Thriftmaster 3/4 ton - Poncho engine swap - Sun Jan 23 2022 03:26 AM
Sorry, to clarify, these are the original brass synchro's and I have a spare trans that has a donor set in great shape, but those are not brass. I was told I should keep the original brass regardless.

For the 2nd synchro, I was referring to what I circled here, is this supposed to look like that?
[img]https://www.stovebolt.com/ubbthreads/ubbthreads.php/ubb/download/Number/38965/filename/Gears.jpg[/img]

Finally, I tore into the trans tonight and the replacement bearings for the front have the correct dimensions, but less bearings in them. Is this a problem?

Yes, that's what I thought you were referring to (what you circled). I think it' a remnant of the machining of the gear, and nothing to worry about.
Posted By: Goach2 Re: 1948 Thriftmaster 3/4 ton - Poncho engine swap - Sun Jan 23 2022 02:17 PM
I was concerned because it doesn't have a consistant pattern like a machine would leave. I'm going to check my spare...

In the meantime, starting to plan for fender reassembly. I know not everyone has the center mount under the rad, but mine is about 1-5/16" unbolted:
[img]https://www.stovebolt.com/ubbthread...umber/39057/filename/20220125_184548.jpg[/img]

This is a new piece, it used to have about 5/8" of steel wedged in there. I'm assuming everything is going to align completely different now, than it did previously. I was thinking about starting with the hood alignment that"s in the tech articles first, then piecing it all together loosely until by some magic I can close and latch it. Make sense?

Just reading the hood alignment process, perhaps the fenders should be 'loosely' in place to do this?

In a bit of a situation with the transmission, so decided to take my mind off of it with another job. Since this is behind the fender, decided to clean it up and paint with POR product

Bought an inner fender edge rubber kit and it came with staples. I know the original rubber was stapled on as well. Is there actually a stapler that will pierce an inner fender metal? I can see myself manually putting a staple through each existing hole...
Posted By: klhansen Re: 1948 Thriftmaster 3/4 ton - Poncho engine swap - Tue Feb 01 2022 11:00 PM
My old office has a big honkin' stapler that was used to staple 50+ pages at a time. I think that would pierce the sheet metal. But I'll likely either do like you're thinking about using the existing holes, or use some glue instead.

IIRC, when I took the old staples out they were round wire. One could just use baling wire.

Looks good did the inner fenders come with this rubber when new .My truck had no rubber but it could have been long gone before I got it.

Yes, most of it was still there. Existing staple holes likely a dead giveaway.

Seems to be some disagreement over the fender to cab beading. I have it ready to go on, but some have said no. It's not a new paint job and I had to scrape of the original, so I know it was there. Keep it?

Both fenders on and supports underneath. Took some work to get it together so far:
[img]https://www.stovebolt.com/ubbthread...umber/39389/filename/20220205_161110.jpg[/img]

For the firewall to fender rods, instructions say left side is 27-1/4" from the center of the bolt head to the edge or brackets.

Is 'left' the passenger side?
Is the center of the bolt the first bolt or the second bolt?

FAM Section 11, Sheet 12.00 shows the dimension to the forward bolt head, but says the 27.25 dimension is for the RH (passenger unless you're in England) side and the LH side dimension is 27.48 inches.

So with hood closed, I have a good 1/2" gap between the hood and the cowl, at the top. I think I will put the grill in place, remove the hood latch plate and do the alignment procedure in the tech tips. It's a little confusing about which hinge bolts it's referring to, but I'll see what I can do to follow along.

This truck lost it's mount under the rad years ago and I had to repair a bunch of stress cracks in the fenders. Knowing that there is likely to be some warpage, should I try for a 1/4" gap? Or go for 1/8" and see if I can get the fenders to align to that?

Got the trans in alone, this wasn't too bad to align it:
[img]https://www.stovebolt.com/ubbthread...umber/39781/filename/20220216_194258.jpg[/img]

Couple things to note for anyone doing it in the future:
- front bearing, I had to use the outside clip from the original, as the replacement was slightly thicker and would not let the front cover piece to sit against the body.
- for the trans alignment pins, the earlier cases have a piece in the casting that don't allow a long pin to be used. I ended up only using a pin on the drivers side to get it in

You a
already have the door off pins and bushings are cheap if they are loose or seized up you can also get the cover plate for a good price if they are rusty or bent up badly.

Well, I rebuilt the master, honed it out as well as it will go, but a few small pits are still causing it to leak. I want to upgrade the brakes, so I will live with it for now (as I have the last 5 years) and upgrade later.

Rad is ready and so is the fuel tank (which was leaking and I dropped it and had it repaired right)

Question about break-in. I have a new valve cover gasket, but no sealant on it. I want to do the 20min @ 2000rpm break-in. I am assuming I will have to do some valve adjustments and don't want to waste a gasket. Can I leave it unglued for break-in and then run some sealant on the block side when it's done? Or will it make a big mess on my newly painted engine?
Posted By: KEVINSKI Re: 1948 Thriftmaster 3/4 ton - Poncho engine swap - Tue Apr 12 2022 07:33 PM
No problem with my gasket it is a cork one I did not put any sealant on it and have had it on and off a few times.

Tank in as well as Rad and brakes bled. Pretty much ready for break-in if there's any tips out there. So far I have 2k rpm for 20 min with my zinc additive, then drive 500miles and redo timing, adjust valves and torque head bolts again.

Anything else?

So this weekend I ended up doing the break-in run, 20 mins at 2k RPM. Did some timing adjustments and carb/idle as well before. The next day I go to start it and it only starts full choke and full throttle and runs like some cylinders aren't firing.

I'm assuming I will have to redo the timing again, but is this normal? Or am I missing something?
