400 ft/lbs of torque applied at 4000 rpm through 2:1 gearing = 800 ft/lbs output and 300~hp at 4000rpm.
800 ft/lbs of torque applied at 2000 rpm through 1:1 gearing = 800 ft/lbs output and 300~hp at 2000rpm.
345 hp 365 ft/lbs will out tow 250 hp 460 ft/lbs any day of the week. It works on paper and I proved it with two Rams identical except for the engines and transmissions towing a 10, 040 lb 5th wheel.
Diesels are stronger. Not necessarily faster. Diesels make better heavy tow rig engines for several reasons. Higher horsepower at lower rpm is the most attractive to rpmaphobes. If you're scared of 4k rpm, then the diesel is for you.
