Ford Navistar 6.9L/7.3L Engine Identification:

6.9L vs. 7.3L: The cylinder head towers are shorter on the 6.9L. A shorter cylinder in effect shortens the stroke of the engine, in effect causing a smaller cubic inch engine. This makes not purchasing the exact replacement rebuilt engine a mistake. Don’t cheat here.

Applications for the 6.9L and the 7.3L are not interchangeable. Truck engines compared to Van engines: The oil cooler assembly and the fuel filter locations are different. Truck and van models are not interchangeable.

Small differences due to different engine compartment configurations between the Pre-1992 and Post-1992 cause the need for different external engine parts in order to fit specific vehicle, necessitating the use of your VIN to establish the exact rebuilt engine you need. For example the pre-1992 engines use V-belt configuration, while post 1992 engines use a serpentine configuration. Ford applications have a rear sump and International applications have a front sump.

Perhaps it is not common knowledge that International Engine Company supplied Ford with their diesel engines until this year, 2009.
