Nevermind, found a calculator on line.
2014 RAM 2500 6.4L Hemi (66RFE, with 0.625:1 6th gear)
65 mph with 4.10s - 1688 RPM
65 mph with 3.73s - 1536 RPM
2007 RAM 3500 5.9L Cummins (48RE with 0.69:1 4th gear)
65 mph with 3.73s - 1779 RPM
Hey IB, where is this calculator at. I'm curious to see what my RPMs will be towing my speeds. I'm also curious what gear I can lock it in to be around the same as my '05 is. My new truck has 3.42s with the Aisin. Same size tires as yours.
