1977-1979 Ford F-Series F-100 VI SuperCab 5.8 351 V8 (163 Hp)

The Ford F-Series F-100 VI SuperCab, produced from 1977 to 1979, represented a significant iteration of Ford’s long-running and immensely popular F-Series pickup truck line. This generation, known internally as the sixth generation, saw the introduction of the SuperCab body style – an extended cab offering increased passenger space. The 5.8-liter (351 cubic inch) 351 V8 engine, producing 163 horsepower, was a mid-range engine option for the F-100, positioned between the smaller inline-six engines and the more powerful 460 cubic inch V8. It catered to buyers needing a balance of capability and affordability, particularly those requiring the added space of the SuperCab configuration.

Technical Specifications

Powertrain & Engine Architecture

The heart of this F-100 variant was the 351 cubic inch (5.8-liter) Ford Windsor V8 engine. This engine, designated as the 351W, was a staple of Ford’s lineup for many years, known for its relatively compact size and robust construction. The 1977-1979 version utilized a two-barrel carburetor for fuel delivery, a common setup for the time, prioritizing simplicity and cost-effectiveness over the more complex fuel injection systems that would become prevalent later. The engine featured a cast iron block and cylinder heads, and utilized a traditional pushrod valvetrain with two valves per cylinder. The 351W produced 163 horsepower and approximately 260 lb-ft of torque. This power was delivered through a standard three-speed manual transmission, although a Cruise-O-Matic automatic transmission was a popular optional upgrade. The engine was mounted longitudinally in the chassis, driving the rear wheels.

Driving Characteristics

The 351 V8-equipped F-100 SuperCab offered a noticeable step up in performance compared to the base inline-six engines. While not a high-performance truck, the 351 provided adequate power for hauling moderate loads and towing trailers. The three-speed manual transmission offered a reasonable balance between fuel economy and usability, though the gear ratios were spaced to prioritize low-end torque for work applications. Compared to the optional automatic transmission, the manual offered more driver control and slightly better fuel efficiency. The SuperCab configuration, while adding interior space, also increased the overall weight of the truck, slightly impacting acceleration and braking performance. The ride quality, typical of body-on-frame trucks of this era, was firm but generally comfortable for everyday use.

Equipment & Trim Levels

The F-100 SuperCab with the 351 V8 engine typically fell into the mid-range of Ford’s trim level offerings. Standard features included a basic interior with vinyl upholstery, a simple dashboard layout, and a functional, no-frills design. The SuperCab added a rear seat, significantly increasing passenger capacity. Optional extras included air conditioning, upgraded audio systems, power steering, and various trim packages that added chrome accents and more comfortable interior materials. The Ranger trim package was a popular upgrade, offering a more refined interior and exterior appearance. The SuperCab’s extended cab provided a useful space for carrying passengers or cargo, making it a popular choice for families and tradesmen alike.

Chassis & Braking

The F-100 VI SuperCab utilized a traditional body-on-frame construction, providing a robust and durable platform. The front suspension consisted of independent coil springs with a transverse stabilizer bar, offering a reasonable level of ride comfort and handling. The rear suspension employed leaf springs, a common design for pickup trucks, providing a strong and reliable setup for carrying loads. Braking duties were handled by disc brakes at the front and drum brakes at the rear. Power steering was often an optional extra, making maneuvering the large truck easier, particularly in tight spaces. Tire sizes typically ranged from 215/75 R15 to 225/75 R15, providing a good balance between ride comfort and load-carrying capacity.

Market Reception & Comparison

The 1977-1979 Ford F-100 SuperCab with the 351 V8 engine was generally well-received by the market. Critics praised the added space of the SuperCab and the engine’s balance of power and fuel economy. Compared to the smaller inline-six engines, the 351 V8 offered a significant performance boost, making it a popular choice for those who needed to tow or haul heavier loads. However, it wasn’t as powerful as the larger 460 cubic inch V8, which appealed to buyers needing maximum capability. Fuel economy, while adequate for the time, was a concern as gas prices began to rise. The 351 V8 was considered a relatively reliable engine, though carburetor maintenance was a regular requirement.

Legacy

The Ford F-100 VI SuperCab with the 351 V8 engine remains a popular classic truck among collectors and enthusiasts today. The 351 Windsor V8 is known for its durability and relative ease of maintenance, making it a desirable engine for restoration projects. Parts availability is generally good, although some specific trim pieces can be difficult to find. These trucks are often sought after for their classic styling, spacious interior, and capable performance. While not the most powerful or fuel-efficient F-100 variant, the 351 V8-equipped SuperCab represents a sweet spot in the lineup, offering a good balance of practicality, comfort, and affordability. Well-maintained examples continue to command respectable prices in the used car market, reflecting their enduring appeal and historical significance.
