What engine came in a 1968 F-100?
There wasn’t a single engine option for the 1968 Ford F-100; it could be equipped with several engine choices depending on trim and configuration.
In 1968 Ford offered both economical inline-sixes and a range of V8s, with some engines introduced or adjusted mid-year. Exact availability varied by options package, cab/bed configuration, and regional emissions rules. The following outlines the main engine families customers could encounter in that model year.
Engine options in the 1968 F-100
Inline-six engines
Inline-six engines were a common baseline choice for reliability and economy in the 1968 F-100. The following six-cylinder options were typically available.
- 240 cubic inches (3.9 L) inline-six
- 300 cubic inches (4.9 L) inline-six
Conclusion: Inline-sixes provided solid torque for hauling and good fuel economy, making them a popular pick for fleet and work-oriented buyers.
V8 engines
For customers seeking more power, Ford offered several Windsor and FE V8s in the F-100 lineup. Availability depended on the vehicle's configuration and year-specific options.
- 289 cubic inches (4.7 L) Windsor V8 (present in some late-1960s trucks)
- 302 cubic inches (4.9 L) Windsor V8 (introduced in 1968; widely used in subsequent years)
- 360 cubic inches (5.9 L) FE V8
- 390 cubic inches (6.4 L) FE V8
Note: The 351 Windsor was introduced for the 1969 model year, so it did not appear in the 1968 F-100 lineup.
Summary
The 1968 Ford F-100 offered a diverse engine lineup rather than a single standard engine. Buyers could choose from 240 or 300 inline-sixes for economical duty, or upgrade to V8 power with the 289/302 Windsor, and the larger 360 or 390 FE engines, depending on the truck’s configuration and production date. This variety allowed buyers to tailor the truck to light, medium, or heavy-duty duties within the 1968 model year.
