The transmission is a rugged four-speed with floor shifter, but some junkyard shopper purchased the engine before I showed up with my camera.
In 1966, the engine choices for the F-100 were the 240- and 300-cubic-inch straight-sixes (making 129 and 150 horsepower, respectively) and a 352-cubic-inch V8 rated at 172 horses. This truck still has V8 exhaust manifolds under the hood, but that doesn't mean its most recent engine was a 352; most old pickups seem to have received at least one engine swap during their lives.
The F-Series went from a solid front axle to a double-I-beam independent front suspension for 1965, so this truck would have been a bit smoother on the fire trails than its predecessors.
This is the last model year of the fourth-gen F-Series; for 1967, a generation of much more modern-looking Ford trucks hit the street.
Someone did an application of body filler on this F-100, prior to its forced retirement, but never got around to sanding and painting.
Ford used paint-sprayer science to prove that the Twin I-Beam suspension provided a smooth ride.
