Ford Super Duty
source: wikipedia
On the extreme opposite end of Ford’s spectrum, the Super Duty is a product of simple truck logic: Bigger is better. Introduced in 1998, the Super Duty incorporates distinctly upgraded chassis and suspension components found on the F-150 and provides higher payload and towing capacities. Ford’s first answer to the Cummins, the 7.3L PowerStroke diesel, pumped out up to 275 HP and an impressive 525 pound-feet of torque. Emissions restrictions meant the 7.3L had to be replaced by a smaller 6.0L, then eventually a 6.4L and the Super Duty now uses a 6.7L pushing out a respectable 440 HP and an even more impressive 925 pound-feet of torque at 1,800 RPM. The PowerStroke’s all-iron block and heads are built to take plenty of abuse for extended periods of high load and the engine’s substantial low-end torque ratings make it one of the most capable trucks ever sold.
