RE: 4:10s or 3:73s
get 4.10s you wont regret it, trust me....I know many people that had 3.73 and they went to 4.10 they said they never go back....I had 3.73s and upgraded to 4.10, there is a hella difference....4.10 just rape off the line, 1st gear is short, but not that bad at all....but for an auto you dont shift so, what the hell go 4.30, LOL its up to you depending on where you go with the car if its a strip car(4.30 or 4.10) or if it a highway driver(3.55 or 3.73), Or if its a street /strip car than hardly see's freeway(3.73 or 4.10). it up to you where your going with the car....yes definitly get shift kit, and stall, I dont know about brands, I have a manual...but get around a 2800rpm stall for stock cars, and B&M makes good shift kits and stalls.

RE: 4:10s or 3:73s
my stall buzzer went off, did someone say stall?
you should buy mine seriously nothing wrong with it. i had a extra VB but that was sold
go with 410s if you care to accerlerate alot. now you if you just want to drive the car stock which you dont but 355 or 373 are for that setup but to get most out of the AOD cars go 410
i with 410s nonlockup stall, 255/50/16 rear tires cruised at 70mph at 2600 rpm off stock tach

RE: 4:10s or 3:73s
The old adage is 3.73 for sticks and 4.10's for autos. The reason being is that 1st gear on a stick is 3.35 or 2.95 while on a auto it is 2.54(?). Multiply the rear gear ratio by the tranny gear ratio = the torque multiplier number. Anything over 10 = good acceleration.
