The 7.3 diesel engine is used in a Ford 50 Super Duty truck, which is comparable to the engine used in the F-250 trucks. Several F-250 and F-350 trucks have many of the same features.
The Super Duty line of Ford trucks come in either gas or diesel. Only the F-450 models are available in diesel alone. The F-250 Platinum features a 6.2L V8 gas engine. An F-350 Platinum and a King Ranch also feature V-8 gas engines and use two-valve technology with the flex fuel option. From there, it is a matter of choosing the other options that the truck has to offer.
