As a lover of classic trucks, I would be hard-pressed to name my favorite year of Ford pickup, but I might choose the 1966 F 100. Let’s review this great truck.

The 1966 Ford F100 marked the last year for the F-Series fourth generation. Ford had redesigned their trucks the previous year (with the new Twin I-beam suspension). The standard engine was a 240 inline 6, optional 300 six cyl, or a 352 ci V8. The F100 had an option for a Camper Special.

The sixties were a turbulent time for America. The Age of Aquarius was dawning as young men fretted about their draft numbers. Anti-war protests were ramping up in earnest even as nightly news programs beamed horrific war images into every living room. Star Trek and Batman debuted on television, the Sound of Music won best picture, and everyone played California Dreaming on the radio. These were days filled with a great longing for change. The ripples of this American conscience left no one untouched, impacting every area of society, including the automotive world. The family car was out. Hotrods and Muscle cars were in. Old trucks were retired as new, more uniform designs took over the American heartland. With the selling success of Chevy’s C10, Ford grew desperate to regain the hearts of the American public. To win back America, they decided to quietly fade out the fourth generation of the F-Series (it’s a shame they did). In my analysis as a classic truck lover, I say that the 1966 F100 is a beautiful beast that doesn’t nearly get the love it should.

What Makes The 1966 Ford F100 So Special?

There are many great features on the ‘66 F100 pickup truck worth mentioning. If you weren’t around in the mid-sixties, please allow me to brag a little about this iconic truck.

Production Numbers

Ford produced 260,873 F 100s in 1966 (over 85% were 4x2 Stylesides). While the Flareside and Stake or Platform versions and shorter beds (6 ½ feet) were available, most buyers appreciated the additional cargo room the 8’ bed Styleside offered.


By the end of 1963, Ford began to realize that their unibody design was a complete and utter failure. Dubbed an “integrated pickup,” the F-series consisted of a seamless cab and bed. The production costs were lower (which pleased the higher-ups), but in their rush to manufacture a more profitable truck, Ford made mistakes. Complaints of the doors jamming (especially when sidewall toolboxes were loaded), panels ripping and tearing, or even beds warping as heavy loads hit the payload area. For 1964, Ford reverted to the separate cab and cargo trucks, extending the wheelbase on 8’ beds and again tweaked the design for the 65 and 66 models.

The 1966 has a rugged appearance, as straightforward as it was simple. Turn signals were situated above the headlights, which bookended a chrome grille holding the iconic Ford letters indented just under the lip of the hood. Two egg crate slots gave the truck’s front an aggressive appearance.

The truck side had a design line shadowed above the side panel and started from the front quarter panel extending through the door and back to the rear. It formed a lip over the rest of the side and matched the slightly flared fender wells. The front quarter panel sloped downward like a waterfall, while the rear flared from the base of the chassis back to the rear in a straight line. Located between the door and the rear fender, a locking toolbox provided quick and easy access for storage.

The tailgate was strengthened with double-walled construction and was supported by heavy-duty steel hinge-type straps that could support up to a ton in weight. The tailgate’s one-pull handle in the center made opening and locking much easier. A two-tone paint option was available for all cab configurations.


The year before (1965) introduced an innovative suspension system called the “Twin I-beam.” Early ads trumpeted the suspension as providing a smoother ride, offering more control, and reducing maintenance because both front axles moved independently. The

sales brochure promised to “pay off in dollars and cents as well as in ride and handling ease” A prolonged chassis/body life would also produce a higher resale value at trade-in time.

The two front axles gave the truck a smoother ride over rugged terrain. The F100 handled curves better because the truck could maintain its ability to keep the tires planted. The importance of the twin-beam suspension cannot be underestimated since it would become a basic component that Ford trucks would have for almost three and half decades.

Engine And Transmission

The standard engine was the 240 cu. in. inline six, with the option for the 300 cu. in. six or the much larger FE 352 cu. in. V8. The 352 is the best of the bunch, packing 208 HP @ 440 rpms and 315 ft/lbs of torque. It featured aluminum alloy pistons, upgraded oil rings, and hydraulic lifters for quieter idle vibrations. The rotary oil pump kept things lubricated, and the larger intake and exhaust valves were designed for better wear over their lifetimes.

While the 352 would be replaced with the 360 in just a couple of seasons (1968), it was still a beast of an engine. They were built with enough power to handle any job truck owners threw at them. The cast iron block made them virtually indestructible.

The standard transmission was the 3-speed direct drive manual, with an option for the 3-speed with overdrive or the 3-speed Cruise-O-Matic automatic transmission. The 3-speed with overdrive was a stout transmission from New Process (NP435) and powered by a lever on the tree. Since it was used so much through the sixties, the transmission is easy to find parts for.

Engine Horsepower Torque
240 cu. In. Inline Six 150 @ 4000 rpm 234 @ 2200 rpm
300 cu. In. Inline Six 170 @ 3600 rpm 283 @ 2400 rpm
352 cu. In. V8 208 hp @ 4400 rpm 315 ft/lb @ 2400 rpm


The Interior of the 1966 Ford F 100 was nothing to sneeze at. The left-hand oversized mirror, padded dash, windshield washers, and emergency flasher were now standard equipment. Seat belts were a part of the standard cab’s vinyl seats made with extra padding for a more luxurious ride. Ford knew that comfort was becoming more of a buying issue for truck owners, so they provided options. The Ranger option included bucket seats with an optional console between the seats.

The oversized tri-spoked steering wheel offered good support over a simple-to-read instrument panel. The gauges were straightforward, wrapped in chrome accents, and an interior dome light was an addition that helped illuminate the cab. A right-hand armrest and cigarette lighter were optional.

Optional Equipment

Power brakes and power steering were options for truck owners of the 1966 Ford F100. The features made parking the truck easier, and pedal pressure was heightened to make the brakes more responsive. Other options included black vinyl seats, a passenger sun visor, and a deluxe fresh air heater and defroster.


The base MSRP for a 1966 Ford F 100 Styleside 4x2 was $2,129 (a bit of money in the mid-sixties). Just to compare, it was cheaper than a ‘66 Mustang ($2,713).

Camper Special

One of the best additions to the F-Series was the option for a camper shell to come with your truck. The camper coach was available on 8-foot bed Stylesides 4x2s (it was not available for 4x4s). While most camper shells ended up on F250s, the owner could add the shell to the bed or purchase a cab/chassis to weld it directly to the frame.
