I used to own a LS1 camaro A4 with 4.10s and I got just terrible gas mileage but could get pull a lot of cars just off those gears alone. Will 4.10s have the same affect on the mustang? It's my daily driver so if not 4.10s what about 3.73s

4.10's on an NA 2v are a great gear! Remember that the 2v is down close to 100hp than the LS1 so it wont make up for that.
is it a solid gear for a daily drive? im just used to the jerk and torque the 4.10s offer. I do miss it!
I get about 18mpg's right now with 4.10's. Before the 4.10's, I got around 19-20mpg's. The gears aren't going to hurt fuel economy that much. As for the performance aspect of it, they were a night-and-day difference. With the 4R70W tranny 4.10's should be the minimal gear to go with. I almost went 4.30's.
Keep in mind that you're going to need some better tires. I had brand new 275 street tires and they still were no match for 4.10's down low.

As stated before FRPP all the way!
I Have been driving with mine in for 7 years and get around 16-17 Cty and 25-26 Hwy well worth the trade off!

4.10's was the first mod i did and its the biggest improvement i think i ever felt on a car. such a minimal price for a lot of low end power.

I have FRPP 3.73 gears and love them, and I still have issues hooking up with the 245/45 size tires if I don't do it right. They really wake the car up and feel a lot more lively. On my 93 tune I average about 17.5mpg in the city and 24 on the highway, and mixed driving I get about 18-19 mpg... It actually improved my city mpg from stock when I run on 87 octane it gets about 18-19.
