You need to go to svtperformance.com. Stock 03 Cobras run mid 12's. Lightly modded cobras run mid 11's and KB Cobras run in the 10's.

Maybe I should have mentioned that I am at 4000ft thats why the times sound off.

The air here is awful. an 03 cobra has to have a few mods to hit mid 12's here.

A stock LS1 only runs a mid 13 except for the occasional freak my fiend with an 03 cobra hit a 13.3 stock in his 03 cobra wich would have been like a 12.80 at sea level.

I used to get on svtperformance.com when I had my cobra but they were less then impressed with my best ET at the time of 13.83. They were telling me I cant drive not understanding that 4000ft of altitude kills HP.

I know what the 03 cobras can do I am just stating what i have personally seen.

Jeeze my cobra only ran 14.0 stock at sea level!

Yeah, that's the best I could do with the 97 cobra vert I had... 03 is a different horse. I thought the 99s did better than that though.

I just went to a mustang drag day at LACR in Southern CAlifornia and i was more impressed with the Mach 1s than the Cobras. It is a very slow track and well over 3,000 feet so the times are way off. The 03 cobras with the KB where well into the 11s and the stock 03 cobras where low 13s and even one ran 14.5 I fiqured the driver sucked. When all the Mach 1s where in the high 13s low 14s all day long. There was even one Mach 1 (430s, DRs and some exhuast mods was it) in the low 13s as fast as the stock cobras.

I ran 14.0+ more often then not. I only dipped into the 13's a couple of times.

I pulled a 2.07 60ft on my 13.83 run normally I got 2.20's
