Stock automatic ring gear ratio for a 94 GT

Anyone know the stock gearing for an Automatic. Someone told me they thought it was around 3.20 but Im not exactly sure where I would find this information.
My car was originally an automatic, but the previous owner swapped in a Tremec transmission but left the rear end the same.

It could be a 2.73, a 3.08, or a 3.27. What does the axle code say in the door jamb?

That, I believe, is a 3.27. I know Z is a 3.08. It is either a 2.73 or a 3.27, but I think it is a 3.27.

I think yours is a 2.73. In 5th gear going 70, what RPM are you turning? Should be something like 1850 or 1900.

Yeah, unfortunately for you, you have a 2.73. At 70 MPH with a 3.08 I turning 2000 RPM, and at 80 it was like 2300 or so.

Ok we got it all straightened out:

M = 2.73
Z = 3.08
E = 3.27
