Carroll Shelby transformed a conventional Mustang into a serious track racer designated as the "GT-350." The fastbacks were shipped from the San Jose, California assembly plant and fitted with a "Hi-Po" 289, 4-speed manual transmission, and included front and rear disc brakes. Additionally, shortened hoods and deleted rear seats with identifying trim were among the visual variation
Starting in 2008, previous 2007 Shelby GT500 Mustangs could be sent to Carroll Shelby's Special Performance Plant in Las Vegas to be rebuilt into a Super Snake, which resembles the 1968 GT500KR, for an additional cost of $27,995. The Super Snake will offer a 605 hp 2.3L Eaton roots type supercharged version with warranty. A Kenne Bell twin-screw supercharged version with "over 725 hp" will also be available, without warranty and a 0-60 time of under 4 seconds. The Super Snake is inspired by the 1967 GT500 Super Snake, a car made by Carroll Shelby for Goodyear Tires.
