New here and looking for some advice. I've got a 2008 502 crate motor in a 57 Chev Prostreet. I'm looking to push the HP to 650/700 without taking the engine apart. Al. heads, cam and new intake with big four barrel is my thinking. I like the heads from AFR but what cam and intake? It's running 9.6 CR now and I want to keep it on pump gas. The internals are all forged from GM.
