Re: 350 or 400 Pontiac engine in '64 4X4?
Quote:
Best way to get a feel for the difference in the engine mount locations and orientation is to look at the differences between the engine cradles. Pontiac V8: https://www.summitracing.com/parts/a...CABEgIqmvD_BwE SBC: https://www.summitracing.com/parts/s...make/chevrolet Personally I would go with the 400 block over any of the others. You can increase the stroke on these engines a lot with very little machine work, and this can be done in your garage with an angle grinder. I helped my brother with his 400 build for his ‘68 Firebird. Final displacement was 461 cubes. Everyone that said it’s expensive is right, a lot more than building a sbc, even more than bbc for the most part. Butler Performance is your best resource for a Pontiac build, and they know their stuff. If you have a bit of money, you can end up with a better (in my opinion) engine for your truck. If you’re deciding between a 400 & 455, go with the 400 block. It has a smaller diameter main journal and will have less friction than the larger main diameter 455 block. Good luck and post your progress.
