consider this
I went from a built aod to a built c4 with the same 3000 stall speed and picked up 3 tenths .I figured it was the less weight of the c4 and the less rotational mass.I don't know exactly how much lighter my c4 is compared to the aod but i know it was alot easier getting that bad boy up in the hole lol.I have since changed from my previous 3.27's to a 3.73 and gained 3 more tenths so I would say it is depending on the converter stall speed and rear gear selection being matched to your combo as to whether or not you will see better times.
