I talked to a ford auto mechanic that said if i go with the 4:10's my mustang gt will get horrible gas mileage is this true? And what is better 3:55 or 3:73 what is the difference? thanks

Well your gas mileage already sucks anyway, but yeah with 4:10 you will sac. gas mileage and top-speed, but your accel. will be sick and youll lke ur 1/4 mile times......if you have a 5-spd go with 3:73.....if u have an auto go with 4:10

No, no, no!

Gas mileage will not go down and top speed is debatable. Get 4.10's or 4.30's.

...............Not another one. Plese use teh SEARCH feature. AT least one per day I guess. Maybe I should just start getting used to seeing:

3.73 vs. 4.10?

4:10s or 4:30s nothing less.... 1/4 mile 4:10 is not a good gear considering your shifting into 4th right at the end. As far as gas mileage goes that statement is false. Your gear will put you in your power band much sooner.

4:10's if you want to pussyfoot it, 4:30's if you want even more speed...

r u ok kid?? gas mileage WILL GO DOWN IF YOU DO CONSTANT HIGHWAY DRIVING, the higher the gear the more rpms u turn in higher gears resulting in more gas being consumed , however if u only do short drive around town from stop light to stop light then 3.73s or 4.10s will do just fine. IF you hav an auto id go 4.10 and 3.73 in a 5 speed, UNless u take several trips to the track i would not go with 4.30s they WILL reduce the life of your engine and cost you top speed as well as gas mileage

I use 4.10s in my car as a daily driver, nearly all highway miles, and my gas mileage dropped a whopping 1 mpg from what i had using stock gears. Get 4.10s and don't listen to the BS put out about horrendous gas mileage drops from those who don't have, and have never had, 4.10s.

dont 4got about the fact you hav a mach 1 so your stock gears were already 3.55,and im sure it was probly a lil more then 1, switching from stock 3.27s to 4.10s is going to cost about 2-3mpg , not horrible but still a drop non the less
