If you're just competing with stock LS1s and you've got a H/C/I fox, you probably didn't do your homework when you selected your parts and screwed up somewhere. Stock LS1s, besides the look on their owner's faces, weren't really even fun to run with my H/C/I fox. I wish my buddy with the '02 1LE Z28 was around to tell you about our races. He went to West Point with me at the time, and I used to absolutely cream him - the famous LS1 3rd gear roll-on and all. I thought it was funny because I watched him post the "Who will win" thread on LS1.com, and I watched everyone explain how slow foxes were. A couple of people told him to be careful, but others criticized them. Stock he went 13.2@109 while I went a best of 11.9@113. Then after he got tired of losing to a decade older car, my '92, he went and put a cam, headers, and a chip w/ tune in it, went from 311 rwhp to just over 400 rwhp, and how do you think he ran? Terrible because he couldn't hook. He still ran only mid-12s. His car was 3400 lbs from the factory, mine was 350lbs lighter and made about 80 less rwhp and beat him through the 1/4 everytime. I was trapping 112-113, and he trapped 116-117, but always ran slower ETs. At that point, it was a decent race, but his car still couldn't hook like mine did and never ran me down. I knew better to race from a roll, but the point of the story is that there's a lot more to racing than power, especially on the street. After his cam and tune, he had as much in his motor as I had in mine. The headers for LS1s were, and maybe still are, expensive - like $1200. The cam was something like $1500 installed, and the tune was roughly $500. Plus they did a couple other minor bolt-ons and labor.
