1979-1981 Ford F-Series F-150 VII SuperCab 4.9 Six (117 Hp) Automatic

The Ford F-Series F-150 VII SuperCab, specifically equipped with the 4.9-liter inline-six engine paired with an automatic transmission, represents a significant iteration in the long and storied history of Ford’s full-size pickup trucks. Produced from 1979 through 1981, this configuration occupied a crucial position in the F-Series lineup, offering a balance between affordability, capability, and comfort for a broad range of buyers. This variant was part of the seventh generation of the F-Series (1973-1979, with carryover to 1980), known for its increased size and emphasis on driver and passenger convenience. The SuperCab designation indicated an extended cab configuration, offering additional seating and interior space compared to the standard cab models.

Technical Specifications

Powertrain & Engine Architecture

The heart of this F-150 SuperCab was the 4.9-liter (299 cubic inch) inline-six cylinder engine. Commonly referred to as the “300 six” due to its later, more famous iteration, this engine was a workhorse known for its durability and low-end torque. The 1979-1981 version, however, produced 117 horsepower and 308 Nm (227.17 lb-ft) of torque. It utilized a single-barrel carburetor for fuel delivery, a relatively simple system compared to fuel injection, but one that proved reliable. The engine featured a cast iron block and head, contributing to its longevity. The automatic transmission was a Ford C6 three-speed automatic, a robust unit designed to handle the torque output of the 4.9L engine. While not known for its quick acceleration, the C6 provided smooth shifts and dependable operation. The engine was longitudinally mounted in the chassis, driving the rear wheels.

Driving Characteristics

The 4.9L automatic F-150 SuperCab was not a performance-oriented truck. Acceleration was modest, and passing maneuvers required careful planning. The automatic transmission, while smooth, lacked the responsiveness of a manual gearbox. However, the engine’s strong low-end torque made it well-suited for hauling and towing. The gear ratios of the C6 transmission were optimized for work, prioritizing pulling power over outright speed. Compared to the available V8 engines (302, 351, and 400 cubic inch), this configuration offered significantly less horsepower and acceleration. However, it provided better fuel economy and lower maintenance costs. Drivers seeking more power typically opted for one of the V8 options.

Equipment & Trim Levels

The F-150 SuperCab with the 4.9L engine and automatic transmission generally represented a mid-range trim level. Standard features included a basic interior with vinyl upholstery, a simple dashboard layout, and a functional, no-frills design. The SuperCab configuration added a rear bench seat, increasing passenger capacity. Optional extras included air conditioning, a radio, upgraded interior trim, and various towing packages. The exterior typically featured minimal chrome trim, reflecting its work-oriented nature. The SuperCab offered a step up in comfort and practicality compared to the standard cab models, making it popular with families and those who frequently carried passengers.

Chassis & Braking

The F-150 chassis was a traditional body-on-frame construction, providing a robust and durable platform. The front suspension utilized independent coil springs, offering a relatively comfortable ride. The rear suspension employed leaf springs, designed to handle heavy loads. Brakes were disc brakes in the front and drum brakes in the rear. Power steering was standard, making maneuvering the large truck easier. Tire sizes typically ranged from 225/75 R15 to 235/75 R15, providing a good balance of ride comfort and load-carrying capacity. The frame itself was heavily reinforced to withstand the stresses of hauling and towing.

Market Reception & Comparison

The 4.9L automatic F-150 SuperCab was generally well-received by buyers seeking a practical and affordable full-size pickup. Critics acknowledged its durability and fuel efficiency, but noted its lack of power compared to the V8 models. It was often seen as a good choice for those who primarily used their trucks for light-duty work and daily commuting. Compared to the V8-powered F-150s, this configuration offered better fuel economy, but at the expense of performance. The 302 V8 was a popular alternative, offering a noticeable increase in horsepower without a significant penalty in fuel economy. The 351 and 400 V8s were reserved for those who needed maximum towing and hauling capacity.

Legacy

The 4.9-liter inline-six engine, in its various iterations, became legendary for its longevity and reliability. The early versions, like the one found in the 1979-1981 F-150 SuperCab, are known to run for hundreds of thousands of miles with proper maintenance. Today, these trucks are sought after by collectors and enthusiasts who appreciate their simplicity and durability. While the automatic transmission may require occasional servicing, it is generally a reliable unit. The 4.9L automatic F-150 SuperCab represents a classic example of American truck design, offering a blend of practicality, affordability, and enduring quality. Finding well-maintained examples can be challenging, but they remain a testament to Ford’s commitment to building tough and dependable trucks.
