WOWZERS!!!!
Just as the big-block GT500 from 1968 was a step up from the GT350, the Ford Shelby Cobra GT500 show car's 450-plus-horsepower, 5.4-liter V-8 is a step up from the 4.6-liter V-8 used in the previous-generation SVT Mustang Cobra.
In fact, the 5.4-liter, 32-valve, supercharged V-8 configuration is similar to that of the 2005 Ford GT supercar, offering the right combination of classic Ford big-block power and modern technology. Using the Ford GT as a blueprint, SVT has given the GT500 more total horsepower than any factory Mustang in the muscle car's celebrated 41-year history.
"We are applying our Ford GT engine experience to the GT500 to bring over 450 horsepower to a much bigger enthusiast audience," says Jay O'Connell, SVT chief vehicle engineer. "It really delivers on the essence of two great names in Ford performance ΓΆβ?¬β?? a mix of SVT's modern-day experience with supercharging and the Shelby GT500's heritage of big-block power."
The result: More than 450 horsepower and 450 foot-pounds of torque.
