THere are some speed calculators out there that work allright.

Or you can jack your car up, crawl under it, and turn the rear wheels and count the rotations of the drive shaft. that'll tell you.

RE: 4:10 Gears
You can chalk your tire and your driveshaft. Have somebody drive the car for 1 rotation of the tires and count how many times you driveshaft moves. The number of rotations will be your gear ratio. If the driveshaft rotates about 3/12 times you have the stock 3.27. Also, what RPM are you at at 70MPH? If its about 2000 RPM, then you have the 3.27 gears.
