1980 Ford F-100: 7th Gen Redesign Specs & Engine Guide

The 1980 Ford F-100 was a clean-sheet redesign and the beginning of the seventh and final generation to carry the F-100 nameplate. After seven years of Dentside production, Ford introduced a truck that was dramatically lighter, more aerodynamic, and more attuned to the fuel economy demands of the era. The new body shed over 400 pounds compared to the outgoing 1979 model, a transformation driven by the second oil crisis and tightening federal CAFE regulations that were reshaping every segment of the American automotive market.

The styling was a clear departure from the Dentside’s flat surfaces and squared-off proportions. The new body featured a lower hoodline, a more raked windshield, and smoother bodyside contours that reduced aerodynamic drag significantly. The front end carried a new rectangular grille with dual rectangular headlamps, and the overall profile was sleeker and more modern. Ford’s designers had studied wind-tunnel data extensively, and the result was a truck that looked purposeful without sacrificing the traditional F-Series presence. The cab was wider inside despite being more compact outside, and visibility was improved in all directions.

The engine lineup was notably trimmed compared to the sixth generation. Gone were the 351M, 400M, and 460 big-block V8s that had anchored the upper end of the Dentside powertrain catalog. In their place, the 1980 F-100 offered two engines: the 300 cubic-inch inline-six at 117 SAE net horsepower and the 302 Windsor V8 at 133 horsepower. The 351W was available in the F-150 but was never offered in the lighter-duty F-100. The downsizing reflected both the weight reduction of the new truck and the market reality that fuel economy now mattered as much as brute power. The 300 Six, with its enormous low-end torque, remained one of the best work engines in the industry and was the ideal match for the lighter platform.

The Twin I-Beam front suspension was carried over and refined for the new chassis, and the rear leaf springs were recalibrated for the reduced curb weight. Ride quality improved noticeably over the Dentside, and the lighter truck felt more responsive in everyday driving. Available trim levels included the base Custom, the Ranger, the Ranger XLT, and the top-line Ranger Lariat. The SuperCab continued on its 139-inch wheelbase, and both Styleside and Flareside bed configurations were offered, though the Flareside was an increasingly rare sight on dealer lots.

The 1980 F-100 shared its platform entirely with the F-150, a detail that would ultimately seal the F-100’s fate. The F-150’s higher GVWR continued to offer regulatory advantages in emissions and fuel economy classifications, and with the new truck’s reduced weight, the gap between the two models narrowed to the point where many buyers saw no reason to choose the lighter-rated F-100. Ford had built a better truck, but in doing so, it had made the F-100’s role in the lineup increasingly redundant. The countdown to discontinuation had begun.
