Shelby American was founded by Carroll Shelby in 1962 to build and market high performance parts and modified cars for individuals. The company has at various times been based in California, Michigan, and Nevada.
Some of the automobiles produced by Shelby American were the Ford Mustang-based Shelby GT350 and Shelby GT500. Shelby American also installed the engines of US-market examples of the legendary AC Cobra which was an AC Ace with a Ford V8.
The company was also highly involved with racing, with Shelby cars winning many races and the first title for an American constructor at the World Sportscar Championship in 1965.
From 1965 to 1967, Shelby American also provided support to Ford for their successful campaign to win the 1966 24 Hours of Le Mans, the first American constructor ever to do so, using the GT40.
With Shelby Daytona, Shelby became one of only three American constructors (along with Ford and Chevrolet) to win a title on the international scene at the FIA World Championships.
