Re: All about gas mileage now.

I would definitely look at changing gear ratios if your are not towing or mudding. That is where the gas is going. I was able to get 16 MPG out of my 325hp 396 that had a 4-speed and 2.41's in the rear...granted it was a Nova but they don't weigh a whole lot less than these trucks.

or maybe an overdrive unit?
