This 1970 Ford F-250 called “Teton” was built by Project 15 Motorsports in Atlanta, Georgia. Under the hood sits a 7.3 L Godzilla V8 producing 625 hp (459 kW) and 650 lb-ft (881 Nm) of torque. The increased output is due to a custom camshaft developed by Willis Performance Enterprises. The big-block motor also has a Holley intake manifold, accessory drive, and oil pan. The truck’s drivetrain starts with a Gearstar 4R100 four-speed automatic transmission paired to an Advance Adapters Atlas 2 transfer case. Power is split between a Currie Dana 44 front axle and Currie Dana 60 rear axle. Both have Eaton Truetrac limited-slip differentials and 4.11 ratio. The truck sits on a custom Roadster Shop chassis featuring a parellel 4-link front suspension and triangulated 4-link rear suspension. A set of Detroit Steel Wheel D-Town Smoothie wheels hold BFGoodrich Mud-Terrain T/A KM3 35×12.5-inch tires. View more photos and details in Offroad Xtreme’s article.
