I don't know why I looked, but the Allison 4000 is the same length as the MT654. It's actually a little shorter? So to keep this fantasy alive, I would also need a rear end with a 4.56 or lower gear. 2000 rpm would get me going to 85 in 6th with a 4.56. That seems about right, but a little less gear would be nice. 73mph at 2000 in 5th.
