im guessing its outta the car, if so easy way

spin pinion over and count the times you spin the pinion over to get the alxe to spin over 10 times.

divide the number you spun the pinion over by ten and that is your gear ratio

or if your lazy like me

count the number of pinion spins to rotate the axle once. this way is quicker, but you have to guess a little. (ex. if it looks like the pinion spun 3.5 times to get one axle spin, you probably have 3.42's)

Well I'm almost sure it is 2.73, my next ? is should I leave it because I'm going with a 3200+ stall on a 400+ RWHP car or should I spend the money for the carrier gears and swap!

I saw in one of the part mags that you can just buy bigger gears for the 2 seris carrier they are a little more money, is this true? and if so what else do I need!
