I had a Cummins M11 (11.1 liter) 350 hp with a manual Eaton 10 speed. That was the orginal setup and it had 550,000 miles on it. I screwed things up when I changed out the trannie to a new Super 10 (half of the gear changes are just a button shift) Putting that new tight trannie in dropped me to about 9.5 to 10 mpg.

I am pretty sure the rear end gear was 3.15
