* 4.6L V8: This was a fairly common gasoline engine option.
* 5.4L V8: Another popular gasoline V8 choice, often preferred for its greater power.
* 6.0L Power Stroke V8 Diesel: This was the diesel option, offering significantly more torque and fuel efficiency for heavy loads. (Note: this was a relatively new diesel engine at the time.)
