The 5.0l was probably the most common Ford truck engine made, simply called the 302 prior to fuel inj. Was used in pretty much all their vehicles at one time or another, especially from 1980 on.
4.6 and 5.4 started being used in 97, with the restyled f150's and light duty f250 that was around for a year or 2.
Before that, it was either the 5.0, 5.8, or the 460 for engine options.[/QUOT
actually Ford started putting the 302 in trucks in the late 70`s....also Ford had the 300 inline 6cyl (tower of power) as a option....
