What engines were available in the 1984 Ford f150?
The 1984 Ford F-150 was offered with five engine options: four gasoline engines—the 4.9 L inline-six, the 5.0 L V8, the 5.8 L V8, and the 7.5 L V8—plus a diesel option, the 6.9 L IDI V8.
This lineup reflected Ford’s approach that year: give buyers practical daily drivability with efficient sixes, ample power for work and towing with larger V8s, and a diesel choice for those prioritizing fuel economy on long hauls or heavy-duty use. Availability varied by trim, cab configuration, and drivetrain, with some engines paired to specific transmissions or axle setups.
