Wow, thats a wicked time for a mild 318. That was in an E body? was it gutted or anything? Im hoping my 340 breaks into 12's with .480" lift cam, 4.56 rear, hooker supercomps 1 3/4's, eddy manfiold, lakewood drag shocks, 70/30 KYB adj in the front ect ect... but im not so sure it will. That port work sounds like it really woke it up.
