I have a 1970 chevelle body with no engine or trans and a 3.73 rear. I would like to build a high compression 454 but it still has to be able to run on pump gas. So what kind of combo do u think would work best. I have about 3,000 to spend on the engine, i have the block already. Also what transmission should i use. I know a Super T-10 would work but i would like to use a T-56 will it bolt up to the 454, and how much can that tranny handle.
