Re: 1970 3/4 step side puller build (blue blood)
So I have been working on engine during this time and have it assembled almost ready to go in truck. Its a 454 crate motor from Gm. I changed pistons to 9-7-1 compression Ported the peanut port heads to flow 260cfm at 600 lift put a factory holley cast iron intake on off 60s 427 vet motor and ported some vortech exhaust manifolds to make it a stock looking torque monster.
