Right now my car has a 396, rebuilt to stock 350 horse specs (10.5:1 CR?). I'm looking to install new heads and a cam for a winter project. My question is, what heads and cam should I be looking at? I'm thinking 9.5:1 CR range, beause right now I get a slight knock when I really lay on it. So, what heads and cam, and what kind of power can I expect from it? Right now the motor's only "go fast parts" are headers, Holley 750 and Edelbrock RPM Performer Intake. Oh, and I don't mind a relatively large cam.
I'd like to see 450+ hp/tq if possible.
Thanks, and sorry for the long post
