The Ford F-Series F-100 VI SuperCab, equipped with the 6.6-liter (400 cubic inch) 400 V8 engine producing 169 horsepower and paired with a three-speed Cruise-O-Matic automatic transmission, represents a notable iteration of Ford’s enduring and highly successful pickup truck line. Produced from 1977 through 1979, this variant occupied a middle ground within the sixth generation (1973-1979) F-Series, balancing capability, comfort, and affordability. The “SuperCab” designation indicated an extended cab configuration, offering increased passenger space compared to standard cab models. This specific engine and transmission combination aimed to attract buyers who wanted V8 power without the expense or fuel consumption of the larger engine options.

Powertrain & Engine Architecture
The core of this F-100 SuperCab is Ford’s 400 cubic inch (6.6-liter) V8 engine. Within Ford’s engine family, it’s known as the 335-series, and was recognized for its robust construction and relatively straightforward design. It featured a cast iron block and cylinder heads, with a two-barrel carburetor handling fuel delivery. The engine employed a traditional pushrod valvetrain with two valves per cylinder. While not the most advanced engine of its time, the 400 V8 was valued for its strong low-end torque, making it suitable for hauling and towing. The Cruise-O-Matic three-speed automatic transmission was a long-standing component of Ford’s lineup. It was a fully automatic transmission, offering selections for Park, Reverse, Neutral, Drive, and Low ranges. The transmission was designed for durability and ease of operation, though it lacked the efficiency of more contemporary automatic transmissions.
Driving Characteristics
The 169 horsepower and approximately 300 lb-ft of torque generated by the 400 V8, channeled through the three-speed automatic, resulted in a driving experience geared towards practicality rather than outright performance. Acceleration was sufficient for everyday driving, but not particularly quick. The automatic transmission’s gear ratios were optimized for towing and hauling, causing the engine to operate at higher RPMs during highway cruising. Compared to the available manual transmissions or the larger 351 cubic inch and 460 cubic inch V8 options, this combination offered a more relaxed driving experience, but at the cost of fuel economy and responsiveness. The rear-wheel-drive configuration and leaf spring rear suspension provided a firm ride, especially when the truck was loaded.
Equipment & Trim Levels
The F-100 SuperCab with the 400 V8 and automatic transmission typically occupied a mid-range position in the available trim levels. Standard features included a basic interior with vinyl upholstery, a simple dashboard layout, and a functional steering wheel. The SuperCab configuration added a rear bench seat, increasing passenger capacity. Optional extras included air conditioning, a radio, upgraded interior trim, and various exterior enhancements like chrome bumpers and trim. The specific options available varied depending on the year and dealer package.
Chassis & Braking
The F-100’s chassis utilized a traditional body-on-frame construction, providing a robust and durable platform. The front suspension featured independent coil springs and a transverse stabilizer bar, offering a reasonable level of ride comfort. The rear suspension employed leaf springs, well-suited for carrying heavy loads. Braking was handled by disc brakes at the front and drum brakes at the rear. Power steering was often standard, simplifying maneuvering the large truck. Tire sizes typically ranged from 215/75 R15 to 225/75 R15, balancing ride comfort and load-carrying capacity.
Market Reception & Comparison
The F-100 SuperCab with the 400 V8 and automatic transmission was generally well-received by buyers seeking a versatile and capable pickup truck. Reviewers noted the engine’s ample low-end torque and the convenience of the automatic transmission. However, fuel economy was a frequent concern, particularly in the late 1970s when gasoline prices were increasing. Compared to the six-cylinder engine options, the 400 V8 offered significantly more power, but at a higher cost and with reduced fuel efficiency. Compared to the larger V8s, it provided a more affordable and manageable option for those who didn’t require maximum towing capacity.
Legacy
The Ford F-100 VI SuperCab 400 V8 Automatic has become a popular choice among classic truck enthusiasts. The 400 V8 engine, while not known for high performance, is generally considered a reliable and durable powerplant. The Cruise-O-Matic transmission is also relatively robust, though it may require periodic maintenance. Parts availability is generally good, thanks to the widespread popularity of the F-Series trucks. Today, these trucks are often sought after for restoration projects or as daily drivers, offering a nostalgic look back at a past era of American automotive history. The combination of the SuperCab’s added space and the 400 V8’s usability makes this variant a particularly desirable example of the sixth-generation F-Series.
