    I just ran my final drive ratio numbers up and I can see that I won't be running 70 down the interstate for any long periods of time. With the 6.2, 465, Doubler (not that it matters), 5.13's, and 42's, my estimated RPM's will be 2873 at 70 MPH. /forums/images/graemlins/eek.gif That doesn't sound too fun to me. But at least I will have a final-drive ratio of 134.2 in low range. /forums/images/graemlins/thumb.gif

    Why would you want to be running at 70 with 42's anyways? 60 puts you at 2400 or so which is just fine for the 6.2.

    With 39.5's 60-65 is about as fast as I want to go, and with 4.56's my rpm's are pretty close to your numbers...
