Your forgetting about the torque multiplication factor of the torque converter. This will be around 2.0 to 2.5 depending. The auto will kill a row boat tranny off of the line because of the torque multiplication factor.
I don't think many truck owners here ricer racers and are concerned about getting off the line quicker.
My data logging shows that the TC does not stay unlocked very long in tow/haul mode with either the 68RFE or AS69RC. It doesn't lock in first, but it quickly locks within a few seconds after the shift in every other gear leaving you locked for a good while in every gear especially with heavy loads.
Now if you want to just mash the pedal down and leave your TC unlocked on every stop just to get to 60 the quickest, then by all means. However, I don't think that transmission and TC will last long doing so.
