I have a couple of fast Mop's
A 9 sec and 10 sec Dart.
Now to my 03 Cobra.
With just changing to 4.10 gears,Short throw shifter and Superchips program it ran a 12.38 in the 1/4 mile with the traction control on.
I've also have seen the Shelby's at the strip struggle with traction and have even helped a couple learn how to drive there cars.
All I'm saying is be careful about the race.
These cars have the T-56 6 speeds and I never missed a shift in my SRT-10 Pick-up.
Good luck.
