Here is the story. I myself have a 72 chevy 3/4 ton 462, with a 462 BB with around 600hp. My friend has a 68 Chevy Camaro drag car With a 555 BB WITH 1000hp. So anyways he's been looking at sheet metal intakes an the one he likes is 3200 bucks. There for I'm going to make him one an for me. I know there will be trial and error. So I know I will be making more than just 2.
