The 1977 Ford F-100 arrived with the most noticeable styling update since the generation’s 1973 launch. A new grille design gave the truck a distinctly different face, and for the first time, rectangular headlights were available as an option in place of the traditional round units. The engine lineup was also rationalized, with the aging FE engines retired from the F-100 VIN tables and the 351M stepping in as the smaller Modified-family V8.
The rectangular headlight option was the most visible change and gave the 1977 F-100 a more modern appearance. Federal regulations had only recently permitted non-round sealed beam headlights, and Ford was quick to adopt the new format. Trucks equipped with the rectangular lights had a grille designed to accommodate them, while trucks with round headlights received a different grille insert. Both versions shared the same surround and overall front-end proportions. The rectangular headlight trucks are easy to identify and have become the more desirable configuration among collectors.
The powertrain lineup underwent its most significant change of the generation. The 360 and 390 FE engines were dropped from the F-100 VIN tables, ending an engine family that had served Ford trucks since 1958. In their place, Ford listed the 351M V8 at 152 net horsepower and the 400 V8 at 173, while the 302 Windsor held at 134 and the 300 Six at 118. The 460 remained the top engine option, though output slipped to 205 horsepower as emissions tuning continued to take its toll.
Inside, the cab received updated trim options. The Ranger XLT benefited from new fabric choices and revised door panel trim. Air conditioning continued as a popular option, as did power steering and power brakes, which were becoming expected equipment rather than luxury add-ons. An AM/FM radio was available, and Ford offered an optional 8-track tape player for buyers who wanted music on the road.
The SuperCab maintained its 139- and 155-inch wheelbase choices and continued to gain market share as buyers discovered the practicality of the extended cab layout. Both the Styleside and Flareside beds remained available on regular cab trucks.
Production was approximately 197,822 F-100 units. The broader F-Series was growing dominant in the truck market, but the F-150, which Ford had introduced in 1975 as an intermediate model between the F-100 and F-250, was gaining traction and would eventually replace the F-100 entirely. For 1977, the F-100 still offered the lighter half-ton configuration, and the combination of updated styling, the 351M/400 engine transition, and the refined Dentside package made it a compelling truck.
