Road America 500 USRRC Sports Car Race, Elkhart Lake, Wisconsin, 1966--Item 491

With its Mustang a runaway success, Ford asked Carroll Shelby to build a high-performance version for the 1965 model year. Shelby removed the back seat, added a heftier suspension and brakes, and modified the 289-cubic-inch V-8 engine to produce 306 horsepower. The street GT350 was potent, but the 360-horsepower competition version, seen here, was meaner still.
