I have a 2002 trans am. It has 2.73 gears in it. Should I change them or not? If I did change them I would only want to go to a 3.23
Would there be any benefit from changing them? If so, what kind of performance gains have you guys seen from doing so? Thanks

i wouldn't go to 3.23 (45 dead spot) because you will end up changing it to 3.73 anyway. go big the first time 3.73 (no dead spots) and you will see a huge difference.

i got 3.23 in my z28 and i m dieing to go to 3.73

Do you drag race it? Do you drive it a lot? Is gas mileage and/or starting line breakage a concern?
Read my thread about my experience with ditching my 2.73 gears in this forum, it might help you make a decision.

I went from 2.73 to 3.42 and have never looked back!

I went from 2.73 to 3.73, only dropped my track times about .15, but has made the car much more enjoyable to drive on the street. Lost about 2 mpg from the swap, driving mostly highway.

less chance to break a set of 2.73 vs 3.42 and 3.73

Miss my 2.73 gears. Turning 2500rpm at only 58mph instead of 72mph sucks!

I don't know how big of difference it is between the vette and Z28 but this chart is right on with my car with RPMs. I have 3:42 out of a Z06 in my Vette and I like it a lot I have been told the 2:73 that came in my car were very sluggish mine was changed before I got it.

if you turned 2500 at 72 you didnt have 2.73's.

i turn just over 2K at 80, according to the chart above id have to do about 100mph to turn 2500 rpm.
