I've had the opposite experience with an A833OD. I run mine with a 3.21 rear gear and while I do wish for a better drop from 1 to 2, I think it is fine and drives great. Cruises at 65 @ 2000 rpm and does fine around town.
There is better, no argument. But now that I am putting the T56 I bought in a different car I have no plans to do anything to the drivetrain on my '74.
