Joe purchased and installed our LS1 camshaft overhaul package, fitting it to his stock 1999 LS1. The only other modification on his car is a catback exhaust system. Even without pushing it anywhere near its maximum potential—considering the stock intake and stock headers/cats—we managed to deliver a smooth, powerful drive that has plenty of “up and go.” This setup is perfect until Joe returns for further performance mods.
