i have 2.73's in mine and looking to go to 3.73 or 3.55's with a auto tranny havnt decided which ones yet. IMO the 2.73's make the motor bog to much but you can run at 80mph with only 2 grand on the tach

4.10's would really wake up that auto. I would not consider the 3.55's on an auto. At the least a 3.73 gear, but i would still do the 4.10's, you'll be satisfied.

i just dont want gas milage to suck because this car is my daily driver. what do u think rpms will look like at 80mph

Here's a calculator. I'm not sure how accurate it is. I'm sure someone will chime in who can tell you first hand how many rpm's you'll be turning.

EDIT: You did not see it because i'm a dumbass, i forgot to copy it.
