The 1970 Ford Bronco Custom represents a radical evolution of the classic first-generation platform, meticulously re-engineered over a five-year period to achieve ultimate performance standards. While the original Bronco was built for utility, this bespoke creation by Prestige Motorsports focuses on overwhelming power and modern technical sophistication. Every component has been upgraded to handle the rigors of high-output off-roading while maintaining a level of finish suitable for the most prestigious auction blocks.

Rugged Modernity and Functional Protection

The exterior character of this Bronco is defined by a utilitarian Gray finish complemented by aggressive wide-body wheel arch extensions. High-strength Tom’s Off Road Impact Series steel bumpers provide essential protection, while AMP Research power-retractable steps ensure easy access to the elevated cabin. Modern illumination is provided by LED headlights and integrated light bars, cutting through the dark with contemporary efficiency. Rolling on 20-inch SOTA wheels wrapped in 37-inch Toyo Open Country M/T tires, the silhouette remains unmistakable yet decidedly more imposing than its factory counterparts.

Luxury Refinement and Digital Integration

The cabin has been completely reimagined with high-end materials, featuring Black and Gray leather upholstery accented by vibrant Red contrast stitching. Technology is seamlessly integrated via a customized dashboard housing a modern digital gauge cluster and a JL Audio touchscreen head unit. Driver comfort is prioritized through a power-adjustable seat and a Billet Specialties steering wheel that provides a premium tactile connection to the chassis. A Bimini top and integrated roll bar offer both safety and an open-air experience, while the body-color rear cargo cover ensures a clean, finished look.

Small Block Displacement and Big Block Power

At the heart of this build is a 351 Windsor block stroked to a massive 427 cubic inches, delivering an incredible 506 hp / 513 PS and 540 lb-ft / 732 Nm of torque. Fuel delivery is handled by a Holley Sniper electronic fuel injection system, ensuring reliable starts and crisp throttle response in varying conditions. The power is managed by a floor-shifted 4R70W automatic transmission paired with an Atlas dual-range transfer case and Wild Horses twin-stick shifters. To manage the massive energy, the chassis utilizes King coilovers and Dynatrac axles, supported by 4-wheel disc brakes with a Hydroboost system for massive stopping power.

Technical Terrain Systems and Control

The mechanical suite is rounded out by specialized electronic and pneumatic aids designed for serious trail work. An onboard air compressor supports the air lockers within the Dynatrac axles, allowing the driver to engage maximum traction at the flick of a switch. The 4-wheel drive system is fully optimized with an Atlas transfer case that allows for independent control of the front and rear outputs. Side-exit exhausts with cut-outs allow the 427 V8 to breathe freely, providing an aggressive acoustic profile that matches the Bronco’s immense physical presence.
