What stood out in 2003
Editorial opinion, based on the criteria listed.
Pick: Ford F-250/F-350 Super Duty with the 6.0L Power Stroke (325 hp / 560 lb-ft, from mid-2003)
Runner-up: Dodge Ram 2500/3500 with the ISB Cummins (305 hp / 555 lb-ft)
The mid-year 6.0L led on both measures, 325 hp and 560 lb-ft, just ahead of the redesigned Ram's new common-rail Cummins at 305 hp and 555 lb-ft, and well ahead of GM's LB7 at 300 hp / 520 lb-ft. Trucks built before the changeover had the 7.3L (275 hp / 525 lb-ft). Editorial pick; a close call on torque.
Criteria: Peak rated torque; Rated horsepower
