Nice job on the mounts. I need to do the same thing I think. I'm going to put a 67 292 engine in my '49 4400 1 1/2 this winter if I can make it fit. Someone said I would have to move the radiator foreward too but I haven't gotten that far yet , still working on the body.
That is a good looking setup- - - -is it home built or commercial? Do you plan to weld or bolt the adapters to the frame? Back when I was working with big rigs, we made it a practice NOT to weld or drill on the frame flanges to attach anything. It creates stress points that can lead to cracks and/or frame rail breakage. I'd suggest drilling holes in the vertical area of the frame and using sleeves over the bolts to position the mount brackets. That might be getting a little too picky, but that's how we mounted things like 5th. wheels, etc. on the big rigs. Jerry

I think the 292 is 3" longer. I have been told you can just move the radiator to the front of the mount. There are smarter people here than me that can tell you that. I will have to move mine into the cab a little because of the 3" blower pulley. I had these mounts made. I think it was classic chassis but not sure. will have to go through my paperwork. I have heard that welding is not the best way to mount. Maybe box the frame? What about hot rivets?
Frame boxing is a surefire way to get it so rigid it cracks. We finally decided to bolt on everything except the roll cage after many years of patching stress cracks on the dirt track cars. We needed enough rigidity so spring rate adjustments would result in predictable handling changes, but the frame needs to flex a little on a street machine. Going from full throttle to idle several times a lap with a 600+ HP engine on a surface that resembled a motocross track after a couple of heat races had a habit of finding the weak spots. Jerry

GM 194-230-250-292 are about the same length as a GMC 6, so no need to move anything if one has a GMC truck. Chevy trucks need to move the radiator into the core support-take a look at a GMC to get ideas.

I made a front mount for my 292 in my 1954 Chevy 3100 and used a 1965 chevy truck bell housing that bolted in the original location. I didnt have to move my radiator at all but its a tight fit. Though I had to put in an electric fan in the front of the radiator.
Beast54 , that looks like what I need to do on mine. Would rather go that route using the front mount than doing any mods to my frame work on putting the 292 in my '49 4400. You didn't happen to save the pattern did ya?
Yes I do have the pattern and boy was it a little tricky to make! It took a few tries to get it perfect. But its strong enought to handle over 400 ftlbs of torque. I made the mount to bolt up to the stock bolt holes on the frame with the 235 i had in there. The rubber mount i got at NAPA, it was from a Ford V10 motor mount. I did have to cut the mount a little shorter and drill an extra hole. The 65 Chevy truck bell housing was a 1/2 inch farther back than the stock 235 one. I did have to beat my firewall a little to give the 292 a little more clearance. You might want to try a 55-59 truck V8 bell housing. But with that thought your water pump pully might touch your raidiator.

Jerry -- You can send me those sketches if you like and we can turn them into a tech tip perhaps -- seems like there's a lot more discussion about the later engines these days as the supplies of 261's and 302's are drying up .... Maybe there's a lot of 'Bolters out there who would be interested in running a 292 in their truck?
Thanks, John

I replied to your new thread about installing the 3rd.-greneration inline engines into earlier model trucks. I'll see if I can add a link to that one. My main concern in suggesting an alternative mounting method was avoiding welding or bolting mount brackets onto the frame rail flanges. We used a procedure on the big rigs for mounting accessories that involved drilling and bolting brackets to the vertical areas of the frame rails, NOT the flanges! Jerry

Hi, I've wound up with the front mount adapter for a 292 and as it's late tonight I will get a dimensioned picture/drawing out to you tomorrow, Have Eric tell you about the engine work he had done, sweet 292... Ted

Ted,Eric, I would also be interested in dimensions and drawing as I am going with a 292 in my 1951 and have been looking for different options to mount it. Thanks Dave

I too would like to see them Thanks all

We can also trace the template on some cardstock or something and mail that out if that works. Here is what ive done to my 292: Chevrolet High Torque 292 300+ HP 400+ Torque Block: 1974 Chevy 292 Crank- Polished Cam- Clifford 264 Hot Street Bored .040 (298 CI) High Compression Forged Racing Pistons Zero Decked 65K HEI Distributor Chrome Moly Push Rods Head: 1966 Chevy 250 Machined .030 Oversized Stainless Steel Valves 1.94/1.60 Bolt Bosses Removed Premium Hi-Flo Lump Port Kit Big Block Roller Rockers Port and Polished Offenhouser 4bbl Intake Edelbrock 600 CFM Carb Pace Setter Full Length Tube Headers 12" Heavy Duty Clutch
I`m also figuring out how to put 292 to my -52 one ton. been searching front mount all over, with no luck, I even bought one horseshoe mount to be modified, did not work. So I would also be interested the pattern for the front mount . I made the side mounts and have the early v-8 bell housing, but maybe the front mount works better with bell housing mounting. -At least that`s the way the motor is originally mounted on these trucks.
I think the front motor mount is a great idea in that it uses the stock position but are there any concerns with its strength and the amount of stress placed on it with such a high torque engine?
Sucking fans are more efficient than pusher fans; since 292's and their brothers are longer than 235's, etc., in Chevy's, ( GMC do not have this problem) it would be a good idea to move the radiator forward slightly in the core support to be able to use an original fan, give more room for accessories. For additional heat capacity, use a fan shroud, with a rolled edge around the fan, fan blades should be centered in shroud. Holes in shroud should have flaps of some heavy material to open when road air pushes them open-see-VW Rabbit, etc.
Neoprene mount material is readily available in 1" thick by 4" wide by length as snowplow blade material; Florida residents will have to look elsewhere.

I see you used the Flathead Ford mount cushions which in my opinion are as good as any ever made. I use then for all motor mounts and many transmission mounts. On my straight eight Buick the engine really rocked and rolled with the factory mounts so I welded some extensions to the timing cover mount plate and used the flathead cushions. No more rocking.
I am looking to put a 292 in my 48 3600. I like the idea of the horseshoe front mount, but I am lost on the rear mounts. My 292 has a bell housing with the angled mounts. My current 235 has the flat mounts. I have found pictures of how to notch and weld the 48 cross member to match up to the angled bell housing. I cannot find motor mounts to put between the bell housing and cross member. Any suggestions?
Thirdtimer: I'm working on getting a 292 set up to install in my 1951 3800. I found this post from several years ago that shows pics and dimensions for a front motor mount. Looks to me like it would be a whole lot simpler and cleaner than the side mounts I have seen in other posts. If you still have this information, I would be obliged if you could send it to me so I can fab one up for my own use. Email is packhousemike@gmail.com Thanks. Mike Jury, North Carolina
Thirdtimer hasn’t been around for over 3 years. I doubt you will get a response.

My 292 has side mounts and transmission mount. If you use a front mount and a transmission mount is that going to put more pressure on the bell housing due to the longer distance between the mounts vs the side mounts that are more centered on the engine?
Hey everyone. just an FYI Thirdtimer had passed away. He was a very dear friend of mine. I now have the template for the 292 front mount. We both designed and built it together. I put a 292 into in my 54 Chevy truck. If anyone wants a copy I can mail one. earadfamily@gmail.com
