the cam u have is crap. sorry, but it is. You get a better cam, bigger mass air, and a bigger throttle body you could probably keep up.
as far as at the 1/4 track, most vette guys (if they ever go) will not know how to race it. The car is set up for autocrossing anyway, so its not going to have the best supension for dragging. You get good 60' times, you should prolly beat them.
