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

7.3L Powerstroke Information:
• 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 truck 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• Though considered outdated when compared to today's diesel technology, the 7.3 was considered to be the leader in diesel technology during the time it was produced.
The 7.3L Power Stroke diesel is regarded as one of the best diesel engines utilized in the light/medium duty market due to unsurpassed reputation reliability, even in the most rugged of operating conditions. During its production, very few 7.3L Power Stroke experienced serious engine problems and the B50 engine life of 350,000 miles proved to be an extremely conservative rating. Though production of the 7.3L Power Stroke ceased in 2003, the engine remains highly sought after in the used diesel truck market.
