Some mag's got a 12.9 out of the camaro, however I'm a little disappointed this GT didn't get a 12.7 or so. The 5.0 is, despite earlier skepticism, underrated to produce an actual 434 HP. So it has 250 lbs advantage, around 8 more HP (even though like 10 less lbs of TQ), and Live Axle for straight line help, and it only manages to crank out a tenth faster than the SS? Only thing I can seem to blame is the 255s.
