The 1977 Ford F-250 Custom pickup represents a classic era of American utility vehicles, known for their rugged durability and no-nonsense approach to work and transport. However, this particular F-250 has undergone a remarkable transformation, blending its iconic vintage aesthetic with thoroughly modern performance and comfort. Acquired by its current owner from the reported original owner in 2019, this truck has been meticulously modified to incorporate the 3.5-liter EcoBoost V6 engine, 6R80 six-speed automatic transmission, and even the complete interior from a 2015 F-150. Repainted in a striking Kona Blue, this F-250 is a testament to bespoke craftsmanship, offering a unique driving experience that merges the charm of a classic truck with the capabilities and refinements of a contemporary vehicle.

Exterior Transformation and Details

The body of this 1977 Ford F-250 Custom pickup has undergone significant restorative and aesthetic work. Bodywork was performed, and an 8-foot Styleside bed, sourced from a 1975 F-250, was expertly installed, ensuring a coherent classic appearance. The entire truck was then repainted in a captivating Kona Blue, providing a deep, lustrous finish that beautifully highlights its vintage lines while adding a modern custom touch. Exterior features include upgraded LED headlights, offering improved visibility and a contemporary look. Chrome bumpers, practical running boards, and a functional receiver hitch further enhance both the utility and visual appeal of the truck. The bed is protected by a durable LINE-X spray-in bedliner, ensuring its longevity and readiness for any task.

Wheels, Suspension, and Braking

This modified F-250 stands on impressive 22-inch Raceline 940M Hostage wheels, finished in gloss black with distinctive milled accents. These large, custom wheels are wrapped in aggressive 37×13.50-inch Maxxis Razr MT tires, providing a formidable stance and robust off-road capability. The truck’s suspension has been significantly upgraded for enhanced ride quality and control. It is equipped with Rancho RS9000XL shock absorbers, which are adjustable for various driving conditions, and rear air springs, allowing for load leveling and a smoother ride. A Volvo power steering pump has been integrated for improved steering assist, and manually locking front hubs offer robust four-wheel-drive engagement. The four-wheel drum brakes were serviced during the build, and the booster and lines were replaced, ensuring reliable stopping power.

Modernized Interior and Infotainment

The interior of this 1977 Ford F-250 has been thoroughly modernized for comfort and technology, with the entire dashboard, center console, power-adjustable front bucket seats, and rear bench all sourced from a 2014 F-150. This integration provides a contemporary driving environment within the classic shell. A Speedway Motors wiring harness was meticulously added to manage the various electrical components, controlling lights, windshield wipers, and the advanced stereo system. Further interior appointments include power front windows for convenience, a touchscreen Kenwood head unit providing modern connectivity, a powerful Rockford Fosgate amplifier, a 10-inch Kicker subwoofer, and Infinity Reference speakers, creating a high-fidelity audio experience.

Driver’s Cockpit and Instrumentation

The driver interacts with a modern leather-wrapped multifunction steering wheel, providing a comfortable grip and convenient access to various controls. Behind the steering wheel, Dakota Digital instrumentation offers a contemporary and precise display of vehicle information. This digital cluster includes a 160-mph speedometer, a 10k-rpm tachometer, a digital information display, and gauges for coolant temperature and oil pressure. The replacement digital odometer indicates a mere 28 miles, a figure that is stated to reflect the mileage covered since the completion of the comprehensive build, underscoring the freshness of the conversion.

Powertrain and Performance

At the heart of this custom 1977 Ford F-250 is a potent 3.5-liter EcoBoost V6 engine, reportedly sourced from a 2014 F-150. This modern, turbocharged V6 is a significant upgrade, delivering a substantial increase in power and torque compared to the original engine, along with improved fuel efficiency. The engine installation included a MARS wiring harness for seamless integration and a Spectre air cleaner for optimized airflow. While the check engine light is noted as illuminated, the seller attributes this to aftermarket wastegates, a common characteristic of performance-tuned turbocharged setups. This EcoBoost V6 transforms the F-250 into a true powerhouse, providing exhilarating acceleration and robust performance for both daily driving and more demanding tasks.

Drivetrain and Chassis Modifications

The power from the EcoBoost V6 is efficiently routed through a 6R80 six-speed automatic transmission, also said to be sourced from a 2014 F-150. This modern automatic transmission provides smooth and responsive gear changes, enhancing both performance and driving comfort. Power can be sent to the rear wheels or all four wheels through a dual-range transfer case, offering versatile capability for various terrains. Drivelines NW driveshafts ensure robust and reliable power transfer. For chassis integrity and compatibility, the front axle and rear section of the frame from a 1975 F-250 were reportedly fitted during the build. The truck is also equipped with a custom fuel tank and a 3-inch MagnaFlow dual exhaust system with catalytic converters, ensuring efficient exhaust flow and a pleasing engine note.
