I've watched a 99 SVT blow away an 89 Trans AM GTA 350tpi and a 89 Cougar XR7 5.0. The GTA only ran a 17. Rear wheel cars have no grip. The SVT just ripped of the line. While the "big boys" were leavin most of their tires at the line.
The only mods on the SVT where an air filter and - the resonator.
