This 1977 Ford F-250 is powered by a twin-turbo 3.5 L EcoBoost V6 and 6R80 six-speed automatic transmission from a 2014 F-150. A dual-range transfer case splits power along Drivelines NW driveshafts to 1975 F-250 front and rear axles. The truck rides on Rancho RS9000XL shocks and four-wheel drum brakes behind a set of Raceline 940M Hostage 22-inch wheels with Maxxis Razr MT 37×13.5-inch tires. The exterior features a 1975 F-250 8-foot Styleside bed covered in Kona Blue paint. On the inside you find the dashboard, console, power front seats, and rear bench taken from a 2014 F-150. You can find more photos of the unique truck on Bring a Trailer.
