Ok I have searched through several forums and I found a lot of 3.73 for stick and 4.10 for automatic that a 3.73 for automatic are a waste but no reason why. A lot of "put 3.73 in and you will know why" or "so and so told me 4.10 for automatic" or "you will be sorry with a 3.73" but no real reason why 3.73 would be a waste and 4.10 is the only way to go. So what is my RPM going to be at 70 and 80 MPH with 3.73 and 4.10 or even (3.90)? Why is 3.73 bad and 4.10 good? Just don't want to make a mistake after spending $500 for gears and install. I do alot of interstate driving and don't want to be going down the road a 4k rpm.
4.10 for automatic why? I have searched

Yea OD is used on the interstate not the track. I do all my driving (most) on the interstate and don't go to the track. 15 miles to work which 8 are on interstate and a lot of road trips in my job. I just want some more jip and to get me out of the drone zone 1800-2300 my new Magnaflow CB and X- Pipe really scream (drone) going down the interstate. Was tempeted to knock the OD off and did a few times but RPM was to high.

This is what I meant in my post terms like the general consensus, the rule of thumb, everyone with auto should,
I just want to kno the facts behind the reason for the gears. I do see some cam dealers and FI say go with 3.73. So if I wanted Stage II cams later would that make a difference?

the higher 4:10 up are the best low luanch and the lower less low end and more high end top speed. 3:55 and lower............3:73's are a decent gear ratio

The reason cam requirements "require" or recommend gears is bc they will get you in the higher rpms faster which is where the cam will really shine.
