The Ford Super Duty engine was a truck engine from Ford Motor Company.

The Super Duty was introduced in 1958, the same year as the FE and MEL series V8 engines, as a replacement for the Lincoln Y-block in truck applications. The Super Duty was available in displacements of 401, 477 and 534 cubic inches (6.6L, 7.8L and 8.8L). These engines were large, heavy, high torque engines and operated at a relatively low RPM. They were never designed as automobile engines and were commonly found in large, industrial use vehicles including dump trucks, garbage trucks, concrete mixing trucks, large buses and other medium and heavy duty trucks of the time. The Super Duty engine was built in Ford's Cleveland engine plant number 2.

The correct power output for the 534 was 253 horsepower.

The 6.6L produced 262 hp (195 kW) at 5000 rpm and 350 lb·ft (475 N·m) of torque at 2500-3500 rpm. The 6.8L produced 301 hp (224 kW) at 4750 rpm and 430 lb·ft (583 N·m) of torque at 2500-3000 rpm. The 7.2L produced 363 hp (271 kW) at 3000 rpm and 490 lb·ft (664 N·m) of torque at 1800-2300 rpm. A marine version, commonly referred to as the "Seamaster" was also available starting in the late 1950s. The Seamaster was available with twin turbochargers, and weighed over 1,300 pounds (590 kg) installed.[citation needed]
