Boss 429 runs a 10 second flat quarter mile pass.

EDIT: since so many people are throwing a fit over this, ill be clear. The DRIVETRAIN of this car is very modified. The REST OF the car is remarkably stock or very close to it.
Very healthy Boss 429 runs a 10.01 at 142 mph pass at the Tulsa Raceway Park in June of 2008 at the Mid America Ford Performance and Shelby meet. Be sure to watch after the pass for a close up video of how stock the body and interior are on this car, and how badass of an engine this car is packing
