Need help deciding on gear ratio

Can't go wrong with 3.73.. They're ideal in a 5 speed but if it was an auto 4.10s would be best

 

1. It's not your daily driver.
2. It's a mustang, you didn't buy it with fuel economy in mind.
3. 4.10s or go home.

 

4.10's in my 96 GT 5 speed and if I remember right I was like 2300 RPM at 65mph

 

You're not going to see a big difference in gas mileage between 3.73's and 4 10's. The mod motors love the higher gear as well. As they say, never fear the gear.

 

THIS.

 

Depending on cruising speed, the difference between 3.73 and 4.10 is like 2 mpg

 

3.73 will let you have a use able 1st

 

I have 4.10s in mine and it's a 5 speed... I wouldn't consider anything else. If I cared about fuel economy, I would have bought a prius instead.

 

for what u have I say 373 I have 410 with a ton of mods I hate them im ab to go with 355s but I have a lot of tq so its not going hurt me but it u do any kinda modding u will have to change the gears soooo I say 373

 

Mostly stock Gt 5spd max I would go is 3.73

Cobra 5spd 4.10s.... they have a few more Rpms to play with

 

no way. I just went from 3.73's to 4.10's. I can barely notice any change in mpg. I'd go with the 4.10's

 

I was saying the difference is pretty small. And depends on if you do a lot of highway or not. I do, and I would notice the difference going from my 3.73 to 4.10 right now. But in a mostly city car it would be hardly noticeable

 

These cars get pretty good mpg it's not uncommon to hear of mid 20's. I doubt your talking a gallon even if you drive aggressive.

 

I've had both and prefer the 373 for street....

 

Go big or go home, 4.30s. My S197 has them and I still get 21-22 mpg on the highway cruising between 70-80.
