After I spent an absurd amount of money on building the motor/tranny it still came down to a drivers race against mildly modded ls1 camaros. My car was an 04 gt and I loved it but started a sleeper project now, my pontiac GTP is putting down 315 to the wheels with a supercharged 3800. Bolt ons, heads and cams should put you in the 400 hp range, F body cars respond well to mods.
