For that small percentage of buyers that aren't satisfied with the 2010 Ford Mustang-based Shelby GT500 that packs a 5.4-liter supercharged V8 with 540 ponies under the hood, Caroll Shelby and his team have prepped an even more hardcore package called Super Snake. Due to go on sale in August, Shelby offers the Super Snake package on the GT500 in two guises, with outputs of 630 and 725 horsepower, the latter offered only on the coupe model.

To improve handling, the Super Snake package adds a race-spec suspension system with adjustable dampers, a short throw shifter and a Baer brake system with 6 piston calipers and cross drilled and ventilated discs. Customers can also opt for a more hardcore Eibach handling pack.

For the interior, the basic Super Snake package adds center gauge cluster, satin door lock knobs and headrests embroidered with the Shelby logo which also appears on the center console.

Once you bring in your GT500, Shelby will charge you $29,495 for 630HP package and $33,495 for the 725HP kit. In both cases, prices including installation but not the donor car - just to make it clear.

Pay no attention to the "2008" on that snake badge. Even though the 540-horsepower Shelby GT500KR was built to celebrate the 40th anniversary of a certain former chicken-farmer's automotive exploits, it seems that neither Ford nor 'ol Shel want the party to end. As a result, Ford and Shelby will produce an additional 746 units of the GT500KR in model year 2009. 541 of those will go to U.S. customers, making for a U.S.-market total of 1,571 cars, which conveniently matches the production run of the original KR. (Never mind those additional foreign-market cars -- they just mess with that warm, fuzzy, marketing-oriented math.)
