Heron GT40 Classic Cars for Sale

History of the Heron GT40

The Heron GT MK4 traces its origins to 1967, inspired directly by the dominant performance of the Ford GT40 at Le Mans that same year. Designed by Ross Baker and built in collaboration with Bob Gee and Chris Cooke, the aim was to create a faithful, high-performance replica of the Ford GT40 MK4, specifically targeted at motorsport competition. Baker’s team spent significant effort gathering technical data and blueprints from the original GT40, striving to echo its defining attributes both in design and engineering accuracy. Construction was halted before completion due to regulation changes in motorsport, specifically a new 2000cc engine capacity limit, which rendered the project obsolete at the time. Despite this setback, the car eventually competed successfully at circuits such as Spa and the Nürburgring.

Model History: Heron GT MK4

The Heron GT MK4 holds a unique niche in sports car history: It does not follow a lineage of production models but rather serves as a standalone project that was meticulously modelled after the Ford GT40 MK4. With no direct predecessors or successors within the Heron brand, the GT MK4 represents the pinnacle of the marque’s racing aspirations in the 1960s, mirroring the engineering advances and competitive spirit of its Ford muse.

Highlights of the Heron GT40

Each Heron GT MK4 was crafted around an accurate steel monocoque frame with tailored fiberglass bodywork, a performance-focused independent suspension using coil springs, and a unique Heron-developed transaxle gearbox. Notably, the original engine was a 327ci Chevrolet Corvette V8, reflecting the racers’ penchant for reliable and potent American powertrains. Early test drives revealed braking performance that required upgrading to match the car’s capabilities, leading to in-period modifications such as enhanced brakes and upgraded coil-over dampers. The Heron GT MK4 participated in European motorsport events, which speaks to its genuine purpose and credentials.

Special Editions and Collectible Models of the Heron GT40

Given the Heron GT MK4's origins as an individual, race-inspired project, each example is unique. There were no mass-produced limited editions, but individual cars were often updated and modified to meet specific racing needs, such as improved braking systems and revised suspension setups to overcome initial engineering limitations. These upgrades are significant markers for discerning collectors and motorsport enthusiasts.

Weak Spots and Common Issues in the Heron GT40

The initial build of the Heron GT MK4 revealed weaknesses in the braking system, which struggled to match the vehicle's performance capabilities until properly upgraded. As with any highly bespoke, low-volume automobile, the uniqueness of components such as the Heron-designed gearbox can pose challenges for maintenance and parts replacement. Potential owners should be especially attentive to custom drivetrain components and suspension setup, both critical for roadworthiness and optimal driving experience.

Engine and Performance, Transmission and Handling

Powered by a 327ci Chevrolet Corvette V8, the Heron GT MK4 delivers period-authentic horsepower to the rear wheels through an in-house developed transaxle gearbox. The use of a steel monocoque chassis and fully independent suspension translates into pronounced rigidity and handling fidelity on racing circuits. The later modifications—like improved brakes and modern coil-overs—ensure the vehicle maintains composure and competence at race pace. The model’s pedigree is enhanced through documented race participation at venues such as Spa and the Nürburgring. Within the Heron marque, the GT MK4 stands as the sole and definitive model, uniquely integrating bespoke engineering with the spirit of 1960s Le Mans competition. The 327ci Chevrolet V8 and custom Heron gearbox distinguish it from typical replicas or kit cars, resulting in a rare vehicle of substantial technical and historical interest.

Interior, Comfort, Exterior and Design of the Heron GT40

The Heron GT MK4 features hand-built fiberglass body panels, shaped using a male plug form for precise contours and period-correct proportions. The steel monocoque chassis echoes motorsport priorities of stiffness and safety, while the interior is focused on racing functionality with lightweight materials and bare, no-frills detailing. Individual cars may feature custom touches reflecting original owner requirements, but standardised luxury or comfort features were deliberately omitted in favour of motorsport authenticity. The body and paintwork were finished by hand, involving extensive laminating, sanding, and filling for the sleekest possible surfaces.

Other Details

The Heron GT MK4 was the result of exhaustive personal research by Ross Baker, including proprietary blueprints both for chassis and bodywork. The construction utilised a blend of spot-welded and riveted steelwork, individual suspension fabrications, and unique transmission solutions—showcasing a one-off engineering spirit rarely matched in classic GT cars.

Summary of the Heron GT40

The Heron GT MK4 is a purpose-designed motorsport replica of the Ford GT40 MK4, constructed in 1967 as a showcase of engineering commitment and period accuracy. Every aspect, from the Chevy V8 engine installation to the Heron transaxle and steel monocoque chassis, was executed to meet the demands of competitive racing. With only a handful built, and each uniquely modified to overcome the era’s regulatory and technical changes, the Heron GT MK4 remains a rare and significant contributor to 1960s race car craftsmanship.
