Is 170 psi compression too high????
Just got my 383 TPI together. I have edel alum heads and KB hyper pistons. Calculated comp ratio is 9.6:1. I just ran a compression check and got 170 psi all cylinders even. This seems high to me. I run 92 octane pump gas. Am I gonna be ok??? Motor sure feels good!
Thanks alot everyone
