Sometimes it can take months for a product to come to market after it’s initially shown to the public, but that’s not the case for Shelby’s latest Mustang. After debuting the 950 horsepower 2012 Shelby 1000 at the New York Auto Show earlier this month, the company is already hard at work building the first customer car at their facility in Las Vegas, NV. The vehicle shown is actually a Shelby 1000 S/C, a track-only version of the car that is rated at an incredible 1,100 horsepower thanks to longtube headers, race fuel and increased boost from the massive 3.6L Kenne Bell supercharger.

As you can see from the photos below, the modifications required to create a Shelby 1000 are so extensive that the entire drivetrain and front suspension have to be completely removed from the vehicle and assembled separately. In addition to the new engine components, the car is also scheduled to get larger front and rear brakes, an all new suspension system, a 9-inch rear end and more.

Check out the photos of the first Shelby 1000 under construction in the gallery below.
