I am working on a BB for my 77 C-10 pickup. My compression ratio will be in the 9.6.1 range with forged pistons. I am running stock 781 large oval port heads. I am having trouble picking out a cam that will give my street/strip truck the tire frying power I am looking for. I don't have a converter or a carb yet so I am open to most combinations. I already purchased an RPM Air Gap for intake duties. I wouldn't mind going to a higher than stock converter as long as it offers acceptable street performance. My heads flow well into .600" of lift. I was looking for something with alot of duration to give my stock heads time to breath. Any suggestion would be appreciated. I want 400hp and closer to 500 lb ft of torque.
