Ford 6.8L Modular V-10

Ford 6.8L Triton V-10 Specs, Power Ratings, History, & Comparisons

Ford introduced the 6.8L Triton V-10 for the 1999 model year as a replacement for the dated, but well respected 7.5L V-8 (460 CID). Whereas the 7.5L produced up to 245 horsepower and 395 lb-ft of torque during its service life, the 6.8L V-10 was introduced with 305 horsepower and 420 lb-ft of torque. It would receive a small performance boost for the 2000 model year, and a 3 valve version of the engine was introduced for the 2005 model year, bumping horsepower to 362 HP and torque to 457 lb-ft in the Ford F-Series. The 6.8L V-10 was retired from the Ford Super Duty platform (non-chassis cab) following the 2010 model year, but remained available in commercial applications through 2019.

The 6.8L V-10 belongs to the Ford Modular engine family and thus shares commonalities with the 4.6L and 5.4L V-8 engines. In fact, the 6.8L and 5.4L share an identical bore diameter and stroke length; the V-10 simply has two additional cylinders. Like the other Modular engines, the 6.8L is recognized under the "Triton" trademark. The 6.8L V-10 competed against three of Ford's Power Stroke offerings; the 7.3L, 6.0L, and 6.4L diesels. While the diesel displayed superior torque characteristics, the V-10's horsepower rating proved favorable against all three engines. Ford's V-10 faired well against its competition in the 3/4 and 1 ton gas engine segment, producing equal or more power/torque than engines of much larger displacement. This includes Chrysler's 8.0L V-10 (310 hp/450 lb-ft) and GM's 8.1L V-8 (340 hp/455 lb-ft).
