94indy

I just bought a KB and going to put it on when I put my AFR 165 competions on. The heads are 58cc, my motor is a stock shortblock (94 cobra 9:1 CR). Will the 58cc raise my CR to much to run the blower. If not about how many lbs could run. If it's going to be a problem, I prolbly will sell the heads and get some with a higher cc in the combustion camber.

I would guess those heads would put your compression between 9.5-10, but I'm not positive.

they should be fine.
