Gears, rpm, and mph

[sage2k]

I have a 94 gt automatic with what I'm assuming is 3.27 gears according to the door sticker (bought this car used) at 60mph im running a bit under 2k rpm maybe around 1900-1950. Does this sound right for a 3.27? What kinda mph/rpm will I be looking at with 3.73s?

You can enter the specs for an auto. You just need the ratios for each gear.

With 3.73 you would be around let's say 70mph at about 2100rpms using 225/55/16 tires.
