The Ford F-Series F-100 VI SuperCab, equipped with the 5.8-liter (351 cubic inch) 351 V8 engine producing 163 horsepower and paired with a three-speed Cruise-O-Matic automatic transmission, represents a significant iteration of Ford’s long-running and immensely popular pickup truck line. Produced from 1977 through 1979, this configuration occupied a middle ground within the sixth generation (1973-1979) F-Series, offering a balance between capability and relative affordability. The SuperCab designation denoted an extended cab configuration, providing additional passenger space compared to the standard cab models. This variant was primarily marketed towards buyers needing a work truck with occasional family or crew transport needs.

Powertrain & Engine Architecture
The heart of this F-100 SuperCab is Ford’s 351 cubic inch (5.8L) Windsor V8 engine. This engine, designated within Ford’s nomenclature as the 351W, is a 90-degree V8 featuring a cast iron block and cast iron cylinder heads. The 163 horsepower output was achieved through a two-barrel carburetor, a relatively conservative valve timing, and a 8.0:1 compression ratio. The engine utilized a traditional pushrod valvetrain with two valves per cylinder. The Cruise-O-Matic transmission, a three-speed automatic, was a mainstay of Ford’s lineup for many years. It was known for its durability, but its shift points were often criticized for being somewhat sluggish compared to more modern automatics. The transmission was fully automatic, with a column-mounted shift selector.
Driving Characteristics
The 163 hp 351 V8, coupled with the Cruise-O-Matic, provided adequate, but not exhilarating, performance. Acceleration was modest, particularly when hauling loads or traveling uphill. The automatic transmission’s gear ratios were geared towards torque multiplication, prioritizing hauling and towing capability over outright speed. Compared to the available 302 cubic inch (5.0L) V8, the 351 offered more low-end torque, making it better suited for work applications. However, the 351 was noticeably slower than the larger 460 cubic inch (7.5L) V8 option. The SuperCab’s extended cab added weight, further impacting performance. The ride quality was typical of a body-on-frame truck of the era – firm and somewhat bouncy, but generally acceptable for everyday use.
Equipment & Trim Levels
The F-100 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 a radio. The SuperCab configuration added a rear bench seat, increasing passenger capacity. Optional extras included air conditioning, power steering, power brakes, upgraded interior trim, and various exterior cosmetic enhancements. The Ranger trim package, a popular option, added features like chrome exterior trim, upgraded interior materials, and a more comprehensive sound system. The specific options available varied depending on the year and regional market.
Chassis & Braking
The F-100 series utilized a traditional body-on-frame construction. The front suspension consisted of independent coil springs with a transverse stabilizer bar, providing a reasonable level of ride comfort. The rear suspension employed leaf springs, which were robust and capable of handling heavy loads. Braking duties were handled by disc brakes at the front and drum brakes at the rear. Power steering was often included as an option, making maneuvering the large truck easier, especially at low speeds. Tire sizes typically ranged from 215/75R15 to 225/75R15, providing a balance between ride comfort and load-carrying capacity.
Market Reception & Comparison
The F-100 SuperCab 351 V8 Automatic was generally well-received by buyers seeking a versatile pickup truck. Critics praised its spacious interior (for the time) and its ability to handle both work and family duties. However, the engine’s relatively low horsepower output and the transmission’s sluggish shifting were common criticisms. Compared to the smaller 302 V8, the 351 offered more torque, but at the expense of fuel economy. The larger 460 V8 provided significantly more power, but was considerably more expensive and less fuel-efficient. The SuperCab configuration, while offering increased passenger space, also added to the truck’s overall cost.
Legacy
The Ford F-Series sixth generation, including the F-100 SuperCab 351 V8 Automatic, remains a popular choice among classic truck enthusiasts. The 351 Windsor V8 is known for its durability and relative simplicity, making it a relatively easy engine to maintain and repair. Parts availability is generally good, although some components may be becoming increasingly scarce. While not a high-performance machine by modern standards, these trucks offer a unique blend of ruggedness, practicality, and classic American style. Today, well-maintained examples command respectable prices in the used car market, particularly those with desirable options and low mileage. The 351W/Cruise-O-Matic combination, while not the most powerful or efficient, is considered a reliable and durable powertrain, contributing to the enduring appeal of these classic Ford trucks.
