Yea, it will be easier with more displacement. But those manifolds are going to make your power curve hit a brick wall. Build for a low rpm power peak. Performer manifold, AFR 180 heads, and a really good roller cam from a cam grinder that can work magic. all the "little things" will count sice your placing such a handicap on yourself.
