What gear ratio is this

Car has a TH-400, 28" tall tire, at 60mph it is at about 2700 RPM.

I know there are calculators for it but I can't find the good one.

FIRST GEAR SECOND GEAR THIRD GEAR
2.48:1 1.48:1 1:1

3.42 gears come out to 2601 rpm.
This is assuming your vehicle mph is correct, you can't go off the speedo if your set up is not calibrated for the rear gear.

just put the car on jack stand and rotate the wheel 360 degrees. Count how many times the driveshafts spins. If it spins 4.1 times = 4:10 gears get it ?
