In February of 1967, Goodyear approached Shelby in regards to participating in a promotional event centered around the launch of their new Thunderbolt line of tires. Shelby agreed, and planning for the event commenced. With a GT500 selected for modification, work got underway to transform the production vehicle into the highest performing Mustang of the era. The heart of the Super Snake was to be a lightweight, heavily modified version of the aforementioned GT40-class 427 cubic-inch V8, including the prior engine’s signature “Bundle of Snakes” exhaust. This t-shirt celebrates the Super Snake and is everything you've dreamed of and more. It feels soft and lightweight, with the right amount of stretch. It's comfortable and flattering for all.
