The Ford F-250 VI Regular Cab, equipped with the 4.9-liter (300 cubic inch) inline-six engine producing 113 horsepower and paired with a four-wheel drive system and automatic transmission, represented a work-focused configuration within the sixth generation of the Ford F-Series trucks. Produced from 1975 to 1976, this variant catered to buyers needing a robust, dependable pickup for hauling and light-duty commercial applications. It occupied the lower end of the F-250 lineup, offering a more affordable entry point compared to the V8-powered models, while still providing the increased payload capacity that defined the F-250 over its lighter-duty F-100 and F-150 siblings.

Powertrain & Engine Architecture
The heart of this F-250 variant was the 4.9-liter (299 cubic inch) inline-six cylinder engine, commonly known as the “300 Six.” This engine, a long-stroke design, was renowned for its durability and low-end torque. It utilized a cast iron block and head, and a two-barrel carburetor handled fuel delivery. The valvetrain employed a conventional pushrod configuration. While not a powerhouse in terms of peak horsepower (113 hp), the 300 Six delivered a respectable 220 lb-ft of torque, making it well-suited for hauling and towing. The engine’s longitudinal front-engine layout was standard for Ford trucks of this era.
The transmission was a Ford Cruise-O-Matic, a three-speed automatic. This transmission was chosen for its simplicity and reliability, prioritizing functionality over outright performance. The 4×4 system employed a transfer case allowing the driver to switch between two-wheel drive and four-wheel drive, providing enhanced traction in challenging conditions. The transfer case was mechanically engaged, requiring the driver to manually shift into 4-High or 4-Low range.
Driving Characteristics
The 113-horsepower, automatic transmission-equipped F-250 offered a utilitarian driving experience. Acceleration was modest, and the truck wasn’t designed for speed. However, the 300 Six’s torque characteristics provided adequate power for everyday tasks and hauling moderate loads. The automatic transmission, while convenient, did sap some power compared to the available manual transmissions. The Cruise-O-Matic’s gear ratios were optimized for towing and fuel economy rather than spirited driving. The 4×4 system added weight and complexity, but significantly improved off-road capability and traction in slippery conditions. Compared to the V8-powered F-250s, this variant felt noticeably slower, especially when fully loaded.
Equipment & Trim Levels
The F-250 VI Regular Cab with the 300 Six and automatic transmission typically represented the base trim level. Standard features were minimal, focusing on functionality. The interior generally featured a vinyl bench seat, a basic dashboard with essential gauges (speedometer, fuel gauge, temperature gauge), and a simple AM radio. Options included upgraded radios, a heater, and various convenience items like a cigarette lighter. The exterior typically featured minimal chrome trim and black steel wheels. The emphasis was on providing a durable, no-frills work truck.
Chassis & Braking
The F-250 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 for a heavy-duty truck. The rear suspension employed leaf springs, designed to handle heavy loads. Braking was accomplished via disc brakes on the front axle and drum brakes on the rear. Power steering was often an optional extra, and power brakes were less common on base models. The tires, typically 215/85R16.5, were chosen for their durability and load-carrying capacity.
Market Reception & Comparison
The 4.9-liter, automatic F-250 was viewed as a practical and economical choice for buyers who prioritized durability and affordability over performance. Critics acknowledged the engine’s reliability but noted its lack of power compared to the V8 options. Fuel economy, while not exceptional, was generally better than the V8 models. Compared to the 302 and 390 cubic inch V8s available in the F-250, this variant offered a lower purchase price but sacrificed significant performance. The 300 Six was often favored by fleet buyers and individuals who needed a dependable truck for everyday work.
Legacy
The 4.9-liter inline-six engine gained a legendary reputation for its longevity and simplicity. Many examples of this engine remain in service today, a testament to its robust design. The combination of the 300 Six and the Cruise-O-Matic transmission proved to be a reliable powertrain, although maintenance is crucial for older examples. In the used car market, these F-250s are sought after by enthusiasts who appreciate their classic styling and straightforward mechanicals. While not a collector’s item in the same vein as some of the higher-performance F-Series models, a well-maintained example of this workhorse truck can command a reasonable price, particularly among those seeking a vintage pickup for restoration or light-duty use. The 300 Six remains a popular choice for engine swaps into other vehicles due to its durability and availability of parts.
