If its auto get4.10 gears,and if its stick get 3.73 gears. Im pretty sure MPG is not effected much, since there is no actual power gain.

you should probably invest in brakes cuz all that power is pointless if u cant stop in time lol.seriously tho u should probably do a h/c/i maybe underdrive pulleys 4.10 s

thats not exactly true...higher(number) gear makes the rpms higher when cruising...so it has a little effect on gas millage...a lot of people say gears dont affect mileage at all...i gotta think that the higher rpms have to use more gas..maybe not much..but the fact that with the new gears ur gonna be punchin it more offen because its more fun..and that uses more gas lol..

I have a lower GT40 intake for sale, PM me if you're interested.

But yeah, do 4.10s, off road xpipe, timing, and a shift kit. Should feel like a different car.
