Sometimes factory stock is not enough. For Carroll Shelby, it has never been, at least not since he introduced his first G.T.350 in 1965. Now the Las Vegas–based Shelby Automobiles will transform a 2010 Ford Shelby GT 500 into a 750-hp Shelby Super Snake. In addition to the engine modifications, the $35,000 upgrade includes a Borla exhaust system, a 6-speed transmission with a short-throw shifter and a 3.73:1 rear-axle ratio, a Ford Racing suspension package, improved braking components, and 20-inch Shelby-Alcoa forged-aluminum wheels. Numerous cosmetic enhancements inside and out complete the transformation. Drive a Super Snake and you might experience your own transformation, morphing—like the cartoon character in driver-education films from the era of the first Shelby—from the docile canine Pluto into a speed-crazed wolf. Pros: The ultimate modern-day muscle car. Cons: It’s bound to get you into a lot of trouble.
