Ford 6.8L Triton V-10

6.8L V-10 Engine Specs, Info

Poor on fuel, good on power - that's been the consensus of 6.8L V-10 owners. The 6.8L was produced for 1999 to 2010 model year Ford Super Duty (F-250, F-350) pickups, eventually being replaced altogether by Ford's 6.2L V-8. Although the V-10's power ratings have varied with model year and application, it was rated as high as 362 horsepower and 457 lb-ft in the Ford Super Duty. It was used exclusively in F-650 and F-750 trucks for several model years before Ford brought the 6.7L Power Stroke to their medium duty platform.

The 6.8L V-10 is a member of Ford's Modular engine family, sharing an identical cylinder bore and stroke with the 5.4L Modular V-8. It has similar known issues as the Modular V-8's, which includes concerns with stripped spark plug threads. For many years, the V-10 offered a powerful, more affordable alternative to Ford's Power Stroke diesel. Despite lacking the diesel's performance characteristics, the engine featured attractive ratings at a much lower price than the diesel upgrade. It's been regarded as a respectable engine platform, despite the fact that it typically provides lackluster fuel economy - it is, after all, a relatively high displacement engine. The V-10 was replaced by the 6.2L V-8 in Super Duty trucks for the 2011 model year, although Ford continues to use the engine in various medium duty (F-650/F-750), chassis cab (F-250 through F-550), and stripped chassis (i.e. motorhome upfit) applications.
