The 1967 Shelby GT500 Super Snake is a one-off supercar built by Carroll Shelby to promote Goodyear’s new range of Thunderbolt economy tyres. It’s for sale at Dana Mecum’s 26th Original Spring Classic Auction on May 14-19, 2013.
Here’s some background:
When Ford redesigned the Mustang in 1967 to take the 390/320 HP big block V-8, Carroll Shelby took the next logical step and introduced the GT500, the first big block Shelby GT, powered by a modified Police Interceptor 428 CI engine rated at 355 HP. Buyers took to the new car immediately, and the car outsold its small block GT350 stable-mate 2,048 to 1,175 units.
In addition to his partnership with Ford, Shelby was also the West Coast distributor for Goodyear, who in February asked Shelby to take part in a promotional event for its new Thunderbolt line of economy tyres.
Shelby judged that the GT500 would be the perfect choice for an extended high-speed demonstration of the new tyre, but the decision took a twist when former Shelby American sales manager Don McCain approached Shelby with the idea of building a supercar that would outperform anything else in the world.
GT500 number 544 was chosen for the task and was rebuilt with a special lightweight 427 racing engine; special rear axle, special transmission and, of course, Thunderbolt tyres. The engine was later described as “the mother of all 427s at that time…aluminium heads, aluminium water pump, forged crank, Le Mans rods, just basically everything inside the engine was built to run sustained 6,000 RPM – to race at Le Mans.
- The one of a king Shelby GT500 Super Snake
- Essentially a GT40 Mk II 427 engine, built specifically for this car
- Purpose-built for the Goodyear Thunderbolt tyre test
- Original Shelby invoice, and Goodyear tyre test photos
- One-off chrome inboard headlight surrounds
- Unique Le Mans Blue hood striping to distinguish the car
- Fitted with passenger car, 7.75×15″ Goodyear Thunderbolt whitewall tyres
- The Super Snake drove 500 miles at an average of 142 MPH and retained 97% of the original tyre tread
- The Super Snake was never mass produced because the projected retail price would have been over twice the price of a baseline GT500 and more than a 427 Cobra
- This prototype was sold in August 1967 for $5,000
