The 1966 Shelby GT350H Fastback remains one of the most clever marketing successes in automotive history. Known as the Rent-a-Racer, this program allowed the public to experience true track performance for a daily fee. This particular example, chassis SFM6S671, is number 671 of the 1,000 Hertz special vehicles produced. It currently stands as a multi-award winner with a deep connection to Carroll Shelby himself. The car will be a focal point of the Glendale 2026 auction this March.
Renowned Restoration and Show Pedigree
Expert restorers Tony and Wayne Conover of Cobra Ranch handled the comprehensive refurbishment of this Shelby. Their work earned the car the Best in Show title at the 2018 Concours d’Elegance of Texas. Perhaps more impressively, Carroll Shelby personally selected this car as his choice at the 2008 Texas Round-Up. The exterior is finished in the classic Hertz scheme of Black with Gold stripes. Additionally, famed artist Bill Neale signed the car, adding a layer of unique memorabilia to the metal.
Documented History and Original Components
Authenticity is verified by SAAC registrar Howard Pardee, confirming the original VIN-stamped engine block remains in place. Shipped new to Burns Ford in Kentucky, it underwent dealer prep before entering the Hertz fleet. The car later moved into private hands in 1967 and has a clear ownership trail in the Shelby Registry. Such transparency is vital for high-tier collectors who demand verified provenance. This history protects the long-term investment value of this high-performance fastback.
Performance Engineering by Wells Racing
The 289 CI HiPo V-8 engine was expertly prepared and assembled by the professionals at Wells Racing Engines. It features CNC-ported K-heads and a Holman Moody FIA solid lifter cam for aggressive power delivery. A Holley 715 CFM Le Mans carburetor sits atop a Cobra aluminum intake manifold. While originally an automatic, it now utilizes a 1993 Mustang Cobra T5 5-speed manual transmission. This modification significantly improves the driving dynamics and highway usability of the vintage machine.
Chassis Upgrades for Competition Handling
Shelby designed these cars with specific suspension tweaks to handle the rigors of spirited driving. This example features lowered front control arms and over-rider rear traction bars for better stability. Koni adjustable shocks and a fast-ratio “Quick” pitman arm enhance the steering response significantly. The 9-inch rear end is fitted with 3.89:1 gears and a Traction-Lok differential. Consequently, the car maintains excellent grip and balance through high-speed maneuvers on the road or track.
Engine Specifications and Power Output
This 289 CI HiPo V-8 is rated at 306 HP and features TRW forged pistons for increased durability. The assembly includes Crower Magnum rocker arms and a Fluidampr SFI harmonic balancer for smooth operation. Exhaust gases exit through Tri-Y headers into a custom 2.5-inch exhaust system with turn-down tips. A high-torque starter from a 1993 Cobra ensures reliable ignition every time the key turns. These mechanical refinements make it one of the most potent Hertz models currently available.
Summary of the 1966 Shelby GT350H
The 1966 Shelby GT350H Fastback is a definitive piece of American racing lore that continues to captivate enthusiasts. This example combines the rarity of the Hertz program with a world-class restoration and elite documentation. Its mechanical upgrades make it a formidable performer that remains faithful to the Shelby ethos. Whether judged on a concours lawn or driven on a backroad, it delivers an unmatched experience. It represents a rare opportunity to own a car with Carroll Shelby’s personal seal of approval.
