57 Chevy gear ratio?

Drive shaft turns 1 and 3/4 turns per 1 turn of the wheel. Can anyone tell my what ratio this might be? Thanks.

It's a 3.55

To check ratio of a non posi, jack up 1 wheel. Turn it one revolution and count how many times the driveshaft turns. Double that and you have your ratio.

I turn the wheel twice so I can skip the math.
