It's tough to beat an original. The '65 GT350 was Shelby's first Mustang and remains one of his best. Carroll modified the K-code 289-cubic-inch V8 Engine to put out 306 horses, took out the rear seat, added side-exhaust pipes with Glasspak mufflers, added a hood scoop, and put a rear battery in select models. Although most people couldn't afford the race-ready price of $4,547, Shelby started an era with this one.
