Ford took on the diesel market by making an alliance with International Harvester Corporation for its 6.9 liter engine in 1983. Due to a few issues, in 1988 Ford requested the 7.3-L engine. Engines of the 7.3-L dimension increased the bore from 4.00 to 4.11 inches. Compression went from 20.7:1 to a 21.5:1. The engine had 185 horsepower with 3000 rpm. At 1400 rpm the engine had 360 ft-lbs of dynamic torque waiting at a driver’s command for pulling and hauling.
