The Ford Shelby I GT 350H 4.7 V8 (310 Hp) Automatic: A Legendary “Rent-A-Racer”

The Ford Shelby GT350H, an iconic variant of the first-generation Shelby Mustang, stands as a testament to American performance engineering and a unique marketing collaboration. Introduced in 1966, the GT350H, where “H” famously denoted its partnership with the Hertz rental car company, transformed a potent pony car into an accessible high-performance machine for the masses – albeit for a limited time. This specific model, the Ford Shelby I GT 350H 4.7 V8 (310 Hp) Automatic, represented a significant chapter in the muscle car era, blending raw power with the surprising convenience of an automatic transmission, making it a distinctive and highly sought-after classic today. Produced from 1966 to 1970 within the Shelby I generation, these vehicles were more than just cars; they were a cultural phenomenon, offering a taste of racing pedigree to everyday enthusiasts.

The Shelby GT350H was a product of the legendary partnership between Ford and Carroll Shelby, a renowned racing driver and automotive designer. Shelby’s mission was to transform the Ford Mustang, originally conceived as a stylish and affordable personal car, into a formidable competitor on the track and a street-legal powerhouse. The GT350H took this concept a step further, integrating a high-performance engine and chassis modifications with the practicality of a rental car, creating a legend that continues to captivate collectors and enthusiasts worldwide.

Engine and Performance: The Heart of the Beast

At the core of the Ford Shelby I GT 350H 4.7 V8 (310 Hp) Automatic was a specially tuned 4.7-liter (289 cubic inch) V8 engine, famously known as the “K-Code” Hi-Po unit. While the standard K-Code produced a respectable 271 horsepower, Shelby American engineers meticulously enhanced it to deliver a robust 310 horsepower at 6000 rpm. This significant power boost was achieved through a series of modifications, including a larger four-barrel carburetor, an aggressive camshaft profile, and improved exhaust headers, all contributing to its exhilarating performance.

The engine’s naturally aspirated design, coupled with a high compression ratio of 10.5:1, ensured a responsive and potent power delivery. Torque output was equally impressive, peaking at 328.95 lb-ft at 4200 rpm, providing substantial thrust through all gears. Despite its performance orientation, the GT350H was primarily equipped with a 3-speed automatic transmission, a deliberate choice for its role as a rental car. This automatic gearbox made the car more approachable for a wider range of drivers, allowing them to experience the thrill of a Shelby without the demands of a manual transmission. For the era, its acceleration figures were outstanding: the GT350H could sprint from 0 to 60 mph in a blistering 5.6 seconds, a performance benchmark that few cars could match in the mid-1960s. Its power-to-weight ratio of 240.3 Hp per tonne (or 4.2 kg/Hp) underscored its lightweight, performance-focused design, ensuring that every horsepower translated effectively to the pavement.

Design and Features: The Iconic “Rent-A-Racer” Aesthetic

The design of the Ford Shelby GT350H was unmistakably Mustang, yet adorned with Shelby’s signature performance enhancements. It maintained the sleek, fastback coupe body style of the standard Mustang, but with several visual and functional modifications that set it apart. The vast majority of GT350H models were finished in Raven Black paint, famously accented with distinctive “Le Mans” gold racing stripes running over the hood, roof, and trunk. This striking color scheme became synonymous with the “Rent-A-Racer” program and remains instantly recognizable today.

Beyond the paint scheme, the GT350H featured functional design elements. A fiberglass hood with a functional scoop helped feed cool air to the potent V8 engine, while side scoops on the rear fenders aided in brake cooling. The car rode on unique Magnum 500 wheels, further enhancing its aggressive stance. Inside, the four-seat cabin featured a sportier ambiance than a standard Mustang, with competition-style seatbelts and a distinctive Shelby steering wheel. While not laden with modern technological features, its strength lay in its pure, unadulterated driving experience. Notably for its time, the GT350H came equipped with disc brakes at both the front and rear, providing superior stopping power crucial for a performance vehicle designed for spirited driving, even by rental customers.

Legacy and Market Impact

The Ford Shelby GT350H’s legacy is deeply intertwined with its audacious “Rent-A-Racer” program. In 1966, Hertz ordered approximately 1,000 GT350H models for its “Sports Car Club” rental fleet, allowing anyone over 25 with a valid driver’s license and the rental fee to experience a genuine Shelby Mustang. This innovative marketing strategy not only provided a unique thrill for customers but also served as a brilliant promotional tool for both Shelby American and Ford. While many of these cars were reportedly driven hard, they introduced countless individuals to the concept of high-performance driving, fostering a new generation of enthusiasts.

Upon their retirement from the Hertz fleet, these cars were refurbished and sold to the public, often at a discount. Far from being forgotten, their unique history and limited production numbers quickly elevated them to collector status. Today, the GT350H is one of the most recognizable and coveted classic American muscle cars. Its competitors in the mid-1960s included other performance icons like the Chevrolet Corvette, Pontiac GTO, and Plymouth Barracuda, but the GT350H carved out its own niche with its unique blend of racing pedigree and rental car accessibility. It symbolized a period when performance cars were becoming more attainable and showcased the ingenuity of Carroll Shelby in bringing high-performance vehicles to a broader audience.

The historical significance of the Ford Shelby I GT 350H 4.7 V8 (310 Hp) Automatic cannot be overstated. It represents a pivotal moment in automotive history, a daring experiment that paid off by creating an enduring legend. Its impact extends beyond its performance figures, embodying the spirit of innovation, collaboration, and the sheer joy of driving a powerful American machine. The GT350H remains a highly valued collector’s item, celebrated at car shows and auctions, a testament to its unique story and timeless appeal.
