Actually, Mack, Cummins Diesel, and Detroit Diesel all offered "High Torque" variations of their engines for use in highway trucks. Remember the Maxidine's? With only a 5 speed transmission, they would accelerate like a car with the high torque built into the governor. All those engines had mechanical governors with certain springs, weights, and rack settings in the injection pump governor that would allow higher torque output at lower RPM's while limiting maximum horsepower at top rated RPM's. A person can use the formula to figure out what maximum torque "could be" at a certain horsepower and RPM, but there are other variables that can be dialed into the governor of a Diesel engine. A gasoline engine with a carburetor is not the same as a Diesel engine in this regard. MikeS.

After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
