T444E is the acronym for Turbocharged, 444 cubic inch displacement, Electronically controlled. The T444E was a popular medium duty diesel used in a variety of applications, which includes extensive use in International school buses. Many of the T444E's applications included vehicles of a GVWR of up to 65,000 lbs. The number of T444E engines produced exceeds 750,000, albeit far from the 2 million+ Power Stroke versions manufactured for Ford.
7.3L Power Stroke vs T444E - Differences Between the Engines
Both engines feature the same basic specifications; the long blocks are identical between both engines. The 7.3L Power Stroke is a T444E save for the following differences:
• The PCM's (Powertrain control module) are different, thus the different power ratings offered between the 2 engines. For example, the T444E was offered in ratings up to 620 lb-ft torque, where as the Power Stroke was only offered with peak torque reaching 525 lb-ft. However, you may also notice that the 275 HP rating of the Power Stroke is much higher than any HP rating of the T444E.
• Accessory drive and various engine sensors
• Turbocharger design
• Water pump design
• The T444E block is painted blue
• T444E uses a mechanical fuel pump, requiring a different camshaft
