I have a 1991 Gmc c2500 with a 5.0L 305. It is a 5 speed manual I am looking to put a cam in it leaning twards a cam that gives me some more torque. Comp sounds good but I dont know much about the engine is it hydrolic or mechanical? What all do i need to change? What should i change. I want to do it right and get the most out of it I can. I also kinda like it to sound nice when its idling.
