Okay, so I just got done watching horsepower tv, and they took these performance cams called like " Laser 4-7 swap cams", and they dynoed the small block chevy motor before and after, and these cams gave that motor 33 horsepower! Just wanting to know if there is something that I should have to do before I get 4-7 swap cams... anything to get beforehand? They're like 90 bucks. Get back at me guys!
