This 1977 Ford F-350 Flatbed Packs a Rebuilt V8 and an Honest Past

Ford’s sixth-generation F-Series, launched for 1973 and nicknamed the “Dentside” by enthusiasts, remains a favorite among old-truck loyalists. A 1977 F-350 currently listed for sale in Erie, Colorado, is a one-ton, two-wheel-drive example fitted with a flatbed, and it carries a $12,000 asking price along with its original manuals, a handful of spare parts, and a fresh engine rebuild.

Under the hood sits a rebuilt 400 cubic-inch V8 rated at 170 net horsepower and roughly 325 lb-ft of torque at 1,600 rpm, paired with a four-speed manual gearbox. The radiator, brakes, and clutch are all new, and the odometer shows 114,256 miles. The seller reports around 12 mpg on the truck’s last long trip.

The flatbed itself wears a 9-foot deck with new wood. A 1977 F-350 carries a 10,000-pound GVWR, and towing capability depends on engine and rear axle — here a 4.10 ratio — with the seller claiming 13,500 pounds. These trucks once served as the basis for countless ambulances and fire apparatus, a nod to their durability.

What stands out is the presentation: original paint, a tidy interior, and a seller who clearly cared for the vehicle over the years. One quirk worth noting is that Ford relocated the fuel tank from behind the seat in 1977 for safety, but the change did not extend to flatbed models. Values swing widely, from four-figure project trucks to roughly $50,000 for exceptional 4x4s or examples with modern mechanicals, and a comparable flatbed recently changed hands for$7,200 — a hint that the asking price may need some flexibility.
