Here is a thought......despite the pulses being dampened by the torque converter, does a 2-step have enough affect on the drivetrain to shorten ring & pinion life? I would imagine that leaving at a higher rpm than what is possible footbraking could as well.

If I had a choice starting from scratch, I'd probably go with a Dana 60. But I'd treat the gears in it as well. I just accumulated too much 8 3/4" stuff over the years and experimenting with ratios was easy.
