FBO Heads,cam,intake C6z making 600+whp NA vs my auto cammed procharged LS3 Corvette 700hp. My car is a few 100# heavier than his with the blower and stock weight alone is a lot more. But overall a great race. He said he had beat a heads/cam 250 shot LS3 so I figured he was about to kill me but he didn't.
