powerstroke

A diesel engine produced by international, and used by the ford motor company in their heavy duty line-up of trucks, including the F-250 and F-350. The most popular powerstroke engine is the 7.3 Liter (also known as int'l T444E) this engine was first unvailed in 1994.5 and ran through 1997 with the 5 speed or E4OD trans, then an intercooler was added in the 1999 model, along with the more reliable 4r100 auto trans. (there was no such thing as a 1998 f-250 or f-350 they don't exist the 97 model continued through 98) in 2003, international introduced the 6.0 Liter powerstroke engine. Although this engine had more power and torque, many still favor the 7.3L engine for their proven reliability. The 6.0 also lacks power in the low-mid range rpm's, where the 7.3 is superior. Both engines, however, are much better than any cummings or duramax engine ever built, which just goes to show you how superior the international engines really are.
