Re: Fuel efficient tow vehicles options?
I'm afraid that comparison doesn't mean much unless the trans is in 1:1 or the trucks have the same trans gear ratios. (btw in the ram 1:1 is 5th gear)
In any event I've owned 5.3L chev and 5.4L fords and they were both pretty weak compared to my 5.7L Ram. By comparison the 6.2 GMC my buddy has much better accelleration/tow power than my 5.7
Torque is torque and gear ratios are gear ratios. Your 400 foot pounds of torque thru a 3.21 rear puts 1,284 foot pounds at the rear wheel.
The Chevy 5.3 with its 330 pounds of torque and a 3.73 rear is going to put 1,230 pounds on the rear wheel.
A 4.3% increase in torque is not going to make much of a difference in the acceleration of the two vehicles. Certainly not a "world" of difference
