Take a look at The Camaro Research Groups decoding page and see if you can make out the stamping on the passenger side axle tube. That'll tell you what's in there, if the ring/pinion haven't been changed.

Jack the car up and support it properly. Make a chalk mark on the driveshaft and turn the drive wheel exactly one complete revolution and count the number of times the driveshaft turns. You'll have to estimate the partial last turn, but this will give you a very close number.

thanks guys, if you had to guess what would it be or whats a comin one for a 307 auto

Usually a highway gear in that combo, but it only takes two minutes to check with one of the two methods that have been recommended to you.

Which "auto" and w/wo Air ???

Could be one of @ four ratioslisted in spec.s...
Somewhere between 2.56:1 ~ 3.36:1...

Need #'s from passenger-side axle tube, if original, to tell - if gears were never changed...
