Well found out the machine shop didn't port the heads or intake. So here are some of the spec's. 4.250 crank, eagle H-beam rods, Ross dished pistons, comp roller rocker arms, comp cam xe268H-10, neutral flywheel, harmonic balancer, performer intake. 9.5 to 1 compression. I've been told by Butler and the machine shop that if I wanted to upgrade, abasically set a new set of heads, intake, and carb. Everything is new in the motor for upgrades later.
