Nice times you should get in the 8's with your new combo. I am in the process of updating my car also, did the same as you and bought a new Indy max raised cam block 4.500 bore and Callies billet 4.500 stroke crank, 572ci. GRP 5500 series rods custom 60mm roller cam .990in .963ex lift and using my predator heads and intake again. Should run pretty good on motor and with a small kit be in the 7's
