I had a 2000 WS6 T/A six speed stock on a 70 degree day pull a 12.9 they really make around 380 390 hp thennnn 300 320 at the wheels!! i did the heads an cam only with headers and complete flowmaster exaust an got 12.00 while spinning the wheels at half track...your SS believe it or not is lighter than its pontiac counter part! now i know a rich lil bastard with a srt-4 has almost 10gs in it an running in the 12s so its not unlikely hes full of shit but when you actually see the car and hear it you will never know alot of assholes put a k/n filter on an think its a whole lot faster than what it is or they beat a SS or WS6 cause the guy just dont know how to drive an think oh man i beat one so i can beat em all
