Ford Mustang Shelby GT350

Based on Ford’s Mustang, which was introduced in 1964 to rave reviews, the Shelby GT350 was essentially a purpose-built racing car available to the public at local Ford dealers. Heavily modified at Ford’s behest by Carroll Shelby, the GT350 dominated American sports car racing in the mid-1960s. With famed driver Jerry Titus behind the wheel, it took the 1965 SCCA B-Production National Championship away from Chevrolet’s Corvette, cementing the GT350’s enduring status as a formidable competitor, both on and off the track.

Shortly after the Mustang’s launch, Paxton Products released its McCulloch centrifugal supercharger kit. In turn, Paxton’s Joe Granatelli approached Carroll Shelby with an eye to supplying the superchargers as an option for the GT350. While Shelby was noncommittal, he did lend a 1965 GT350 to Granatelli for development and testing, and upon his return with the modified GT350, he easily outran Shelby himself, who was behind the wheel of a 289 Cobra. Suitably impressed, Shelby ordered 500 Paxton supercharger kits from Granatelli. Shelby American claimed that the kit provided a remarkable 46% horsepower increase, but due to the hefty $549 price tag, only 11 GT350s were fitted with the optional supercharger in 1966. In fact, the 1967 release of the big-block GT500, priced only $200 higher than a similarly equipped GT350, reduced demand for the supercharged GT350 even further. According to the Shelby American World Registry, just 28 supercharged GT350s are known to have been built between 1965 and 1967. However, both Shelby American and Paxton products continued to offer the supercharger in kit form for approximately $430 during the mid-to late 1960s.

This car was auctioned off by RM Auctions in January of 2009 at the Arizona Biltmore Resort & Spa, Phoenix, Arizona.
