What engine is in a 1977 Ford F-150?
The 1977 Ford F-150 could be powered by several engines; the most common were the 302 cubic-inch V8 and the 300 cubic-inch inline-six. Other V8 options were available on certain trims or heavy-duty configurations.
In 1977, Ford’s half-ton F-Series offered a spectrum of engines across the lineup, with choices ranging from a robust inline-six to multiple V8 options. Availability depended on the truck’s configuration, cab and bed, and the emission controls in force at the time.

Below is a representative overview of engines offered across the 1977 F-Series lineup. Exact availability for a given truck would depend on trim and options.
