Ford 6.8L Triton Engine

The Triton is a 6.8 liter, naturally aspirated V10 engine from Ford Motor used to power heavy duty trucks and cargo vans like the Ford E-Series. Featuring a single overhead cam design (SOHC), in a V configuration, the Ford Triton architecture has been part of the Ford Modular family since 1997.

This engine shares its bore and stroke with the Ford 5.4L V8 and utilizes a split-pin crank with 72° firing intervals and a balance shaft to quell vibrations typically associated with a 90° bank angle V10. In 2005, it went from a 2-valve to a 3-valve design, allowing it to receive significant increases in horsepower and torque. While simple and often categorized as rudimentary, the Ford 6.8L Triton engine remains a trusted workhorse within Ford’s heavy duty lineup of trucks, stripped chassis, and cutaway applications for buses, mail trucks or other vital commercial vehicles.  The Ford 6.8L Triton engine powers the following vehicles:
