The Stovebolt Site Forums The Shop Area General Truck Talk Sos 37 Owners - Double Question

Hello Folks!

I run across a small problem, and that is with a very nice 235 engine Ive located. First can anyone tell me what all these numbers mean?

I 15 8 on top of the starter motor - on the block. Then some more numbers..3764476

Then on the cylinder head it has numbers ..3836841 and right under it GM11

Then Ive got a question about a Muncie SM 420 Transmission.. Both of these have aproximately 6000 miles in total on the rebuilds.

I believe the 235 engine mount has the front Engine Mount as does the 216 in the 37 at present. So Ive been told.

I can get the driveline with this package. Now in order for it to fit the rearend I may have to have the entire drive shaft cut or shortened. Since Im not an expert at this. After shortening it and its welded how can these be BALANCED so it doesnt "jump rope" out of balance sort of speak..

I do want to keep the old rearend. Install Patricks Ring and Pinion. Patricks opinion was to keep the rearend and stock transmission but install the 235..

The transmission and engine are in VERY nice condition. Just broken in..

Can you experts give me advice on this. Sure would be nice.
Thanks
and Best Wishes To All from - The Land of The Midnight Sun!

The block casting number says its a 235 from 1956 to 1962. The I 15 8 means it was cast on September 15, 1958 when coupled with the block casting number.

It sounds like a good find! On which side of the pond did you find it?

Päivää Poika!!! Mitä Kuuluu?

Hauskaa Joulua!! I hate to admit that I haven't learned any more Finn. But I remember some Finn cuss phrases that my Dad used!! How do you do those umlauts?

We had St. Urho Day's parties at the Helsinki Bar in Butte, Montana. We could save 50 cents on the sauna if we brought our own towels.

There are some great Finn regions in the US, mostly in logging and mining country. It takes a hard worker to be a logger or miner.

If you want to keep the original rearend you might want to find a original type 4 speed trans that will bolt to the torque tube,to put that 235 in your 37 you will need to use the original bellhousing and if you use the 235 flywheel you will have to use the newer starter. If the 235 is a 55 to 62 you will have to get a shortened water pump and even with it there is no room to run a fan as its still too close to the radiator and the water pump is farther down on the block and you will have to use a electric fan. If I had to do it over again I would use a 54 motor as it uses the same water pump as the 216s,I have a 57 235 in my 37 hooked to the original trans a rearend for now but hope to hook up a S10 5 speed and a S10 4X4 rearend in the future.

The 37 does have the original transmission. And it
does shift freely. It is a 4 speed. Should I just
use that original transmission and install the nice 235 instead of playing around with the Muncie? I do understand that I need a short water pump and flywheel from the 216..

It sure feels "Great" to see my old friends here.

If you have an original '37 four speed it will be a crashbox- no synchros. The 4 speed wasn't synchronised until the SM420 came out in 1948.

Hey There 4 on The Floor!

What is your opinion about this: id just like to
keep the original transmission if it will work
together with this 235 which I think it will but
The Double Clutching learning will be a Fun Experience Especially for the wife..

What do you mean by the term "Crash Box"?
PS sometimes I get stuck on these English Terms
or Slang!!

Hey Heikki- Simplest would be to just use the '59 235 that you have found and stick with the stock transmission and rear-end if they work good for you. You may need a different flywheel to bolt to the 235, depending on which flywheel you have now. I can't remember, does your '37 still have the original '37 216? I think it did. If the '59 engine does not have the (2) studs hanging down on the front mount plate, they can be added or your 216 front plate can be used on the 235. On a '39-'40 truck you can move the radiator to the front side of the mount and use washers or spacers to shim the radiator ahead 1/2-3/4" to get some fan clearance. Maybe you could do something similar on your '37? As Jeff said, it does get very tight between the engine and radiator even with the short pump. An aluminum flex fan can help save space too.

If your wife doesn't like shifting the early 4-speed, you may want to try a '37-'39 pickup 3-speed. They shift easier. Or maybe adapt a '40-'46 3-speed in for the 2nd and 3rd gear synchros. Would take some u-joint and/or driveshaft work to get the later splines to match the '37 torque tube and rear, but I'll bet it could be done.

My 235 is mounted in the front. Is that the two studs you are referring to?

Heikki!

'Crashbox' is slang for a non syncromesh transmission. You already know about 'double clutching', which is the method used to provide smooth shifting of those transmissions. Some folks who were not very adept at that procedure would try to 'force' the gears and consequently created a great 'clashing' and 'grinding' of gears; or, 'crashing'. Hence; 'crashbox'. (lots of people still try to shift that way!!)

Here's the link to a similar situation in the Engine and Driveline page:

This guy is putting a GMC 302 into his '37 truck. There is talk about simply moving the radiator forward. Anyway, this thread may be of help to you. Includes pics.

I saw this on ebay,maybe it will help you out.
