So your saying that a 02-03 Vette is faster than an 03 Cobra? I ran 12.89 @ 112.35 bone stock in my 03. I would hope that would give a 02-03 LS1 Vette a run for it's money. As far as Z06's from the same year, a pulley, chip and CB puts the Cobra out front. I thought this was common knowledge. Where the hell have you been for the last 2 years? Surfing too many Volvo performance Websites?
