The Ford F-Series F-150 VI SuperCab, specifically equipped with the 5.8-liter (351 cubic inch) V8 engine producing 163 horsepower and paired with a three-speed automatic transmission, represents a significant iteration in the long and storied history of Ford’s full-size pickup trucks. Produced from 1977 through 1979, this configuration occupied a middle ground within the F-150 lineup, offering a balance between capability and affordability. It was part of the sixth generation (1973-1979) of the F-Series, a generation known for its increased size, comfort, and focus on versatility. The SuperCab designation indicated an extended cab configuration, offering limited rear seating – a relatively new feature for pickup trucks at the time.

Powertrain & Engine Architecture
The heart of this F-150 variant was the 351 Windsor V8 engine. This engine, a mainstay of Ford’s lineup for years, was known for its durability and relatively simple design. The 5.8-liter displacement was achieved through a 4.00-inch bore and a 3.50-inch stroke. The engine utilized a two-valve per cylinder configuration and relied on a carburetor for fuel delivery – typically a Motorcraft 2150 series two-barrel unit. This carburetor, while reliable, wasn’t known for maximizing fuel efficiency or performance. The Cruise-O-Matic three-speed automatic transmission was the standard pairing, offering a relatively smooth, if not particularly sophisticated, driving experience. The transmission was a fully automatic unit, utilizing a torque converter to multiply engine torque. It lacked the overdrive gear found in some later transmissions, impacting highway fuel economy.
Driving Characteristics
The 163 horsepower and approximately 265 lb-ft of torque provided by the 351 Windsor were adequate for typical pickup truck duties of the era, but it wasn’t a performance-oriented configuration. Acceleration was modest, and passing maneuvers required planning. Compared to the available 302 cubic inch (5.0L) V8 or the larger 460 cubic inch (7.5L) V8 options, this 351 offered a compromise. The 302 was more fuel-efficient but lacked the low-end grunt for heavy towing, while the 460 provided significantly more power but at the expense of fuel economy. The automatic transmission’s gear ratios were geared towards maximizing torque for hauling and towing, rather than achieving quick acceleration. The first gear was relatively low, providing good off-the-line power, but the wide gear spacing meant the engine often operated at higher RPMs on the highway.
Equipment & Trim Levels
The F-150 SuperCab with the 351 V8 and automatic transmission typically fell into the mid-range of available trim levels. Standard features included a basic interior with vinyl upholstery, a simple dashboard layout, and manual windows and locks. The SuperCab configuration added a small rear seat, though legroom was limited. Optional extras included air conditioning, an AM/FM radio, upgraded interior trim, and various towing packages. The exterior typically featured bright trim around the windows and along the body sides. The availability of options varied depending on the specific year and regional market.
Chassis & Braking
The F-150 chassis was a traditional body-on-frame design, providing robust durability and load-carrying capacity. The front suspension utilized independent coil springs with a transverse stabilizer bar, offering a reasonably comfortable ride for a truck. The rear suspension employed leaf springs, which were well-suited for handling heavy loads. Braking was accomplished via disc brakes on the front wheels and drum brakes on the rear. Power steering was standard, making maneuvering the large truck easier. Tire sizes typically ranged from 215/75R15 to 225/75R15, providing a balance between ride comfort and load-carrying capability.
Market Reception & Comparison
The 1977-1979 F-150 SuperCab with the 351 V8 and automatic transmission was generally well-received as a practical and versatile pickup truck. Critics noted its comfortable ride (for a truck) and its ability to handle a variety of tasks. However, the carburetor and three-speed automatic transmission were often criticized for their lack of fuel efficiency compared to newer technologies. Compared to the six-cylinder engine options, the 351 V8 offered significantly more power, making it a popular choice for those who needed to tow trailers or haul heavy loads. Against the larger V8s, it represented a more economical option, though with a noticeable performance deficit.
Legacy
The 351 Windsor V8, in general, has proven to be a remarkably durable engine. Many examples are still on the road today, a testament to its robust design and relatively simple mechanics. The Cruise-O-Matic transmission, while not as sophisticated as modern automatics, is also known for its reliability. However, age and accumulated mileage can lead to issues such as carburetor wear, vacuum leaks, and transmission slippage. In the used car market, these F-150s are sought after by collectors and enthusiasts who appreciate their classic styling and straightforward mechanicals. They represent a bygone era of pickup truck design, when durability and practicality were prioritized over fuel efficiency and advanced technology. Finding well-maintained examples is becoming increasingly difficult, but they remain a popular choice for restoration projects and classic truck enthusiasts.
