The 1966 Shelby GT350H Fastback stands as a unique chapter in American automotive history, successfully bridging the gap between high-performance track engineering and the commercial rental market. Originally part of the famed Hertz Rent-A-Racer program, this specific chassis, SFM6S1260, was delivered to Chicago on April 5, 1966. While most Hertz units wore black and gold, this example is presented in the rare and striking Wimbledon White and Gold Shelby livery. Now enhanced with a period-correct Paxton supercharger, this 1966 Shelby GT350H Fastback successfully offers a visceral and authoritative presence that few small-block muscle cars can emulate.
Wimbledon White Livery and Gold Hertz Stripes
The exterior visual character of this 1966 Shelby GT350H Fastback is defined by its clean Wimbledon White paint and iconic gold racing stripes that transition over the fastback roof. This rare color combination sets it apart from the standard black Hertz fleet, highlighting the aggressive silhouette and functional fiberglass hood scoop. The body retains its original Shelby VIN plate and verified Ford confidential serial numbers, ensuring the vehicle’s historical integrity remains intact. Polished trim and period-correct wheels complete the aesthetic, successfully creating a look that is both elegant and undeniably focused on competition. Every angle of the car reflects the purpose-built nature that Carroll Shelby intended for his GT350 program.
Black Vinyl Cabin and Autographed Glovebox
Inside the cabin, the 1966 Shelby GT350H Fastback maintains its race-ready atmosphere with a standard Black vinyl interior and deep-bolstered bucket seats. A significant highlight is the glovebox door, which bears the authentic signature of Carroll Shelby, accompanied by a certificate of authenticity. The driver interacts with a floor-mounted 4-speed manual shifter, a rare and highly desirable upgrade over the automatic transmissions found in many Hertz units. Understated gauges and a purposeful dashboard design successfully prioritize function over flair. This cockpit serves as a time capsule of 1966 performance, including unique historical artifacts like a Hertz promotional matchbox and original Rohm & Haas Plexiglas care instructions.
Supercharged 289 HiPo and 4-Speed Manual
Performance is anchored by a 289-cubic inch HiPo V8 engine, which has been elevated with the addition of a period-correct Paxton supercharger. This forced-induction setup allows the small-block V8 to deliver a factory benchmark of 306 hp/310 PS and 329 lb-ft/446 Nm of torque, though actual output with the supercharger is considerably higher. Power is funneled through a 4-speed manual transmission to a rugged 9-inch rear end, ensuring the mechanical delivery is as authoritative as the engine’s whine. The engine compartment is highly detailed, showcasing the mechanical complexity of the HiPo build. On the road, the combination of high-RPM stability and supercharged torque successfully creates a driving experience that redefined the pony car segment.
