    Question Engine Mounts on 250 / 292

    Hi All,

    I have a 1965 1st Gen GMC Handivan with a tired 250 currently and have someone looking to swap me a fresh built 292 for another engine I have on another project. I have read that the 292 engine mounts are in a different location. Can I just use the mounts off my 250 on the 292 and they bolt up? or is there some other consideration (i.e. 292 doesn't have bolt holes drilled in the same place or block is a different size or....)?

    Thanks,

    Merc359

    292 Engine Mount

    The 292 has the passenger side motor mount location further forward than the 250/230/194 series six cylinder engine. There are mounts available that will allow you to mount that side to our existing crossmember but they block the mechanical fuel pump. Some members have made custom mounts that allow use of the stock mechanical fuel pump and also bridge the gap between the crossmember and the more forward mounted 292 motor mount. If you don't mind getting rid of the mechanical fuel pump, the commercially available ones could be the way you want to go. Be aware that the 292 is taller than the 250 so doghouse clearance is an issue to consider.

    That's very helpful. I wasn't aware of the height difference. Given that I'm going to be using Clifford dual carb setup and don't know how much clearance I'll have, that worries me. Any idea of how much height difference there is? Changing to an electric fuel pump isn't a problem, but good to know that this is "a thing" to be aware of. Nothing worse than getting deep into a job and finding that out.

    Too much information to rewrite. Better if I can send you some pics and answer your questions directly.

    i have a 292 with clifford dual intake. the 292 is 1 3/4" taller but the webbers are shorter than the stock carb. i lowered my engine an inch +/-. I added spacers between the crossmember and frame rails to drop it. the tranny would need dropped too if you do that. the easiest way to address the offset motor mount is to buy the adapter from 12 bolt tom or make one from plate steel. (I custom made a crossmember and switched to small block mounts). you will need an electric fuel pump, spend a little more and get a good low pressure/high volume pump. I used a carter vane pump and was less than $100.00. dont forget the fuel pressure regulator if running the webbers! the clifford intake will be extremely tight!!! i reversed the carbs and ran a pusher cable for the throttle (much easier!). even doing so, I still needed to drop the passenger side of crossmember another 1/4" to 'lean' the engine slightly. when hooking everything up, I dropped the pass. side down on the leaf spring to have room to work and raised it back up afterwards. the slight lean wasnt noticable and ran it a couple years before making the custom crossmember offsetting the engine another 1/2". I am also using the clifford headers. they fit easily but exhaust was a project in itself. if your buying cliffords complete kit, expect some extra work fitting it in an early but well worth it!
