1954 Ford F-100 Pickup
Additionally, a change to the F-Series naming scheme would remain in place to the present day. The half-ton F-1 became the F-100 (partially influenced by the North American F-100 Super Sabre); the F-2 and F-3 were combined into the F-250 while the F-4 became the F-350. Conventional F-Series trucks were F-500 to F-900; COE chassis were C-Series trucks.
The 1953 F-100 was the last year for the flathead engine in the US. Models in Canada, however, (Mercury M-Series), retained the flathead. 1954 saw the introduction of the new 239 CID overhead valve Y-block V8, dubbed "Power King." The six-cylinder engine's displacement was also increased from 215 to 223 CID and power steering was introduced as an option. In 1955 the 239 Y-block was replaced with the 272 and 292.
