what rear end ratio came in a 72 Cutlass
What rear end ratio originally came in a '72 Cutlass with a 350 engine ? I'm going to put a 700R4 in mine and don't want to have to change the rear end, but am concerned it could be too low for the overdrive.

You'll find all the gear ratio options in the 1972 SPECS booklet on Wild About Cars.

I've had three '72 Cutlasses (350 2v, 4v and 455 4v) and all came with a 2.73:1 ratio. Of course, you'll have to check to make sure.
Wildaboutcars is a great source for that info and plenty more if you register.

That's interesting because in 72 the 2.56:1 gears weren't offered for any of the A bodies, however it was the standard gear for 1971 CS with AT. Is your car by any chance a very early production car? You can tell by the VIN and the cowl tag build date.
