What is the name of the 1965 Ford Mustang tuned by Carroll Shelby?

The 1965 Ford Mustang tuned by Carroll Shelby was the Shelby GT350.

Shelby American transformed selected high-performance Mustang fastbacks into the GT350 beginning in 1965. Carroll Shelby’s team modified the cars for stronger road and track performance, helping Ford compete in the Sports Car Club of America’s B-Production racing class. The work included suspension changes, upgraded brakes, a close-ratio four-speed transmission, freer-flowing exhaust hardware, and engine modifications.

The 1965 GT350 used Ford’s 289-cubic-inch K-code V8. Shelby advertised 306 horsepower, compared with 271 horsepower for the standard K-code engine. Early cars were painted Wimbledon White, with Guardsman Blue Le Mans stripes available as an option. A competition version, the GT350R, was built specifically for racing.

The Shelby GT500 did not arrive until 1967 and used a larger engine. Mach 1 and Boss 302 were later Ford Mustang performance variants, not the name of Shelby’s original 1965 conversion.
