Shelby American adds SCCA-ready version to the GT350 Mustang mix

Enthusiasts who want to take the new GT350 Mustang racing in Sports Car Club of America events are getting some help from Shelby American. The Las Vegas-based company, which upfits the 2011 Ford Mustang GT to create the GT350 Mustang, will add a normally aspirated version to the lineup. When Shelby American first announced the GT350 program in January, it centered on a supercharged version of Ford's new 5.0-liter V8 that would make about 500 hp.

The bi-fuel option will cost buyers $11,000, on top of the price of the pickups.
