Shelby American has finally released the specs on its 2011 Shelby GT350. Starting with a 2011 Ford Mustang GT, Shelby utilizes Ford's 5.0-liter V8 engine but ups the ante a bit. The base GT350 is rated at 430 horsepower (the stock GT musters 412 hp). On the standard GT350, a Whipple supercharger can be added to boost power output to 525 hp – enough to propel the modified Mustang from 0-60 miles per hour in 3.7 seconds. If that's not enough, the R tune version produces a monstrous 624 horses.
All 2011 Shelby GT350s are fitted with a long list of performance-aiding parts which include upgrades to the brakes, suspension and tires. As you can see above, they also wear unique Shelby aero and trim bits, a GT350 45th anniversary badge and a serialized Shelby GT350 dash plate.
Pricing for the naturally-aspirated Shelby GT350 conversion is set at $26,995 and the base supercharged car runs $33,995. Due to the 99-pony jump with the R tune, you would expect that package to cost close to $40,000, but it doesn't. It's just 750 bucks over the price of the standard supercharged kit. All of these prices, however, fail to include the cost of the donor Mustang GT. A full parts list and more performance stats are available in the press release after the jump.
