I stand corrected! Ford does NOT offer a 373 on a SRW F-350 Diesel:( Since I don't want a dually I may have to look at Dodge. Again, thanks guys, at least I have some idea of what MPG is.
Ford doesn't put 3.73 rear ends in their srw trucks because it would be foolish to have a 3.73 rear end coupled to their 6r140 transmission and the powerstroke engine in a srw pickup. People don't realize how the 6 speed transmissions and high torque of the new engines work together to provide huge off the line torque. The new Ford with a 3.55 rear axle is capable putting of over 11,000 lbs of torque on the rear axle in low gear. A 2004 Cummins with 4.10 rear end would put 5600 lb ft of torque on the rear axle in low gear. At highway speeds when not towing a general rule is that the slower the engine turns the better your fuel economy will be. If you are towing at highway speeds you don't really want your truck in overdrive.
