Default 3:73s or 4:10s with 4L60E??

Hey! I have a 98 Z28 with stock gears and an 4l60E and am wondering whether to go with 3:73s or 4:10s?! How can I determine what my top end and highway rpms will be at??

It depends on your hp, if you are running around 400 hp 3.73 is good, I use 3.42 on 360-370 hp.

If the car is a daily driver i would say go for 3.73's. Do you know if your car has stock 3.23's or 2.73's? If it has the 3.23's i wouls say save your money on the gears and just get a converter, better bang for the buck.
