gears and gas mileage
just wonderin'... because my dad's got a 5.4 f 150 and he had the 3.73 gears put in the rear end and he gets about 20-21 miles a gallon which is almost unheard of for a v8 like that. he'll also get 17 or 18 towing something. so all this talk about gear swaps just brought to mind the 4 10's and 8.8 rear ends and all these other combo's. what would be the advantages and disadvantages. just another curious.
