I acquired an ‘82 60 series recently. Fair amount of rust, but engine and driveline seem strong. Thinking of putting the 2F,4 speed and 3:70 pumpkins into Coyote. Current set up is 1F 3 speed and 4:10 gears. Not really planning on any serious off-roading.Would this get me enough mpg increase to make it worthwhile?
