Yep, i'm sure this question's been asked 4,000 times. Ima ask it one more. lol Heres the breakdown, stock '86 gt. Only gettin exhaust(shorty headers, h pipe, flow 40's) and gears. Driver is torque hungry 17yr old who can't afford gas. lol Should I do 3.55's or 3.73's? No major plans for a long time.[/align]

for added mpg go 3.55 but there won't be tons difference between the two ..Iike 3.73's personally

Def 3.73's.

natbel08

go 3.73

for the record im still saving up for them

i thought about that for a really long time cause im kinda in the same spot as you

the reason why i decided 3.73 is because i dont think that the little bit of more gas mileage is worth the much bigger difference that 3.73's make over 3.55's

I used to be dead set on the 3.55's but I've started reconsidering the 3.73's after my friend got a set. His city mpg actually increased because he needs less throttle to accelerate and could shift into 5th sooner. On the highway he still gets ~22mpg as opposed to the 24 or so he was getting before.

As was mentioned there isn't a significant difference between the 3.55 and 3.73 gearset but after seeing how my friend's car reacted to 3.73s I am considering going with the slightly steeper gear. I still have my 3.08s but I have driven my friend's GT a couple times and the difference is noticeable.
