I agree with TX it is a 3.07 or a 3.73. If you install a 3.73 and had a 3.07 it will feel like you just added 50# of torque, but your top end will be limited by engine rpm. If you have a modified cam you need to match your rearend ratio, and tire size to when your cam is coming in. If gas milage is no problem I would find an Eaton LSD and 3.73 gears. Now is the time to go 5 lug and upgrade to front disc. My to cents.
