4.10 is too much.

Pros: You'll be in fifth gear quickly
Cons: You'll be in fifth gear at 110 mph, hope you enjoy being at 2700 RPM on the highway, too.

3.73s are a much better choice for nearly everyone.

4.10s are the only gear to go N/A unless your auto then 4.30s. The rpm difference in 3.73 and 4.10s on the highway is like 200-300rpm lol. So while your enjoying 2700rpms on the highway, the 3.73 guys will be enjoying 2500 rpms lol

I use to be of like mind, but now I've come to realize... 200-300rpms is 200-300rpms. And I would much rather be going down the freeway at 2,400rpms than 2,700rpms.

945LSTANG

you described my thoughts exactly. lol

lilcrate

why? Is your car that loud?

945LSTANG

on a trip 200-300 rpms will significantly effect gas mileage.

I have an O/R X pipe with flowmaster 40 series dumped before the axle so right around 2,700 it really starts to resonate. But also like 945LSTANG said, over a long trip, that will really make a difference.

It's funny how people worry about getting good gas mileage in their Mustang. I mean people buy Mustangs to mods them or go fast in and yet they worry about gas mileage? I don't understand that.

money spent is money spent man....

im not looking for some kind of crazy econobox gas mileage. im fully aware that i have to fill up frequently and was aware of what i was getting into when i bought the car. its just nice to be able to save money when possible.

There is a difference between just being reasonable and being ridiculous. In the summer time I like to drive my car to work a lot. Which is mostly freeway driving. I don't think it's unreasonable to want to maintain respectable gas mileage while doing this.

What I find funny is people with poor engine set ups who try to hide behind their gear.
