Changes to the 7.3 liter engine in 1994 gave birth to
the 7.3 liter Power Stroke. By 1999, International had built 1 million 7.3 Power Strokes, and the 2 millionth 7.3 was built in 2002. Unfortunatly, the 7.3 failed to meet strict emission requirements and therefore was replaced early in 2003 by the 6.0 liter Power Stroke. The 7.3 is largely responsible for making the Power Stroke name legendary, as well as fueling the diesel performance race between the big three.

Interesting Facts:

- The 7.3 Liter Power Stroke is similar to the International T444E. The T444E is essentially the same engine as the 7.3 Power Stroke, but the "Power Stroke" name is only designated when the engine is used in Ford trucks. Power output and maximum RPM are the only significant differences between the engines. T444E stands for: Turbocharged 444 cubic inch Electronic (as in electronically controlled).

- The T444E has been made available in applications above 60,000 lb. GVWR, and extremely popular in the medium duty market while it was available.

- The 7.3 Liter Power Stroke was ranked in Diesel Power Magazine's top 10 diesel engines ever produced. Over 2 million 7.3 liter Power Strokes are still in operation today.

- Over 2 million 7.3 liter Power Stroke equipped Ford trucks are in operation. That's more than Chevrolet, GMC, and Dodge diesel equipped trucks combined.

- Though considered outdated when compared to today's diesel technology, the 7.3 was considered to be the leader in diesel technology throughout the time of its existence.
