Well I went to the track yesterday evening for ride along night. I was pretty impressed with my car. It's a stock ls3 car with a Z06 intake and npp exhaust. The car went 12.38 at 114 with 20in wheels in the rear and 19in up front. I was pretty surprised being 1299 feet above sea level. Looking to put headers, x pipe, 3600 stall, air intake, and nitrous with tune. Trying to run low 10's high 9's on spray. Probably going to Mill the heads. Looks like from what I have read that will get the job done. Also going to run 04 c5 Z06 wheels with drag radials for tires. Any other ideas?
