I'm trying to figure out what cam to run in my 383 tbi engine. I was told that the cam in it right now (comp cams xtreme 4x4 hydraulic cam) Doesnt have enough lobe separation at 111*. The engine is a pre 87 4 bolt main block that has a scat 383 kit and World sportman heads. I dont want to put a roller cam in because of cost and its going into my blazer that doesnt see much over 4000rpms. I plan on upgrading to a larger tbi, injectors, chip, etc. and smog is not an issue. Can anyone tell me if I can make this cam work or is there a better cam to run?
