High Performance 318ci

I’d probably need to get some custom grind cam to use the heads and bring the power band lower. But this cam is 2500-6200 according to manufacturer.

But there probably basing that on 340/360 displacement, cid and head cfm are also gonna decide where your engine makes power. 318 vs 408 powerbands are gonna be at very different rpm's even with the same heads cam etc...
