text: Modifications At the request of owners, a number of Shelby GTs were modified in various ways by Shelby Automobiles in Las Vegas. One of these modifications results in a model known as the Shelby GT/SC (Supercharged). A large number of add-ons could be had including the "Super Snake" brakes, as well as larger wheels and tires which were necessary to accommodate these brakes. Additionally there were three different available superchargers, again installed by Shelby Automobiles or authorized Shelby Mod Shop, that can increase rated horsepower to 550* max H.P.. These include the Ford Racing Whipple and the rare Paxton superchargers. *Superchargers were limited because the 4.6 engine did not have forged internal crankshaft and pistons.
