The engine is a package. It is a compromise between goals, finances, and acceptable behaviors. So before any part is picked, before the cam especially gets picked, you should have worked out all the details. Answer honestly.
1>What do you do 90% of the time with the car? (show, cruise, race, road race)
2>How much money do you have for a budget?(remember..casr are a mix of engine and other stuff. You need to change the other stuff too in almost every case)
3>What parts does your car currently have on the enigne, the trans, the rear, the suspension, the cooling system?
4> How much maintenance do you want to do, and what interval?
Stock engines with warmer cams will be fine for about 50% of people, depending on use. A .500 lift cam is about max for pistons with no valve reliefs (stock), and vlave guides will contact spring retainers if you get too much past .520 lift.
So waht do you want from your car?
