There are actually quite a few Mustangs that are classified as a Shelby GT500. Assuming you mean the current version (2011), the Shelby GT500 sports an amazing 550 horsepower and 510 ft.lb. of torque. The 2010 model did it with 10 less horsepowers clocking off at 540. The original 1966 GT500 had 440 BHP.
