I have $500 dollars for my birthday and wasn't sure what to do with it. I wanted to know some good mods I can get with it. Please no one tell me to save up and get long tube headers or something like that. I already have a K & N intake and programmer and I did a resonator delete. I've heard of getting 6.1 heads and bolting them right on to the 5.7. Other guys tell me I can get 20 rwhp from a dyno tune on top of my 93 Diablo tune, or to go with anl exhaust X pipe and Magnoflows or even get ported throttle body.
