HELP!!!3.55 to 3.73 or 4.10 in my 07 GT

I was wondering how much worse my gas mileage will be going from 3.55 (manual trans) to 3.73 and 4.10.. I don't mind shifting more, I was also wondering what my rpm will be at 50 60 70mph in 5th gear cruising I'm at like 2k in 5th at 70 on the highway. I don't mind the louder exhaust tone either I just really want to know how much it's going to hurt me gas wise.. Gas is insanely high and my mustang is my DD

Go 3.73.

Only about 3 mpg not very noticeable for the big acceleration increase

3.55 to 3.73 is not going to be worth the money. If you are going to do gears and have 3.55s then it's best to step up to the 4.10s. Gas isn't going to be as bas as everyone makes it out to be.

Why waste your money, only old men and people scared about gears go 3.73, and that whole if you go FI you can't have 410s is even stupider.

I had 355 then went to 410s nice jump, tho sometimes I lay awake at night wishing I went to 430s lol

You gotta really ask yourself "do I wanna jump off the line" or " do I wanna save on gas". If you want gas go 3.55 if you wanna have fun 4.10's, but I'm sure you bought her to have fun it pays to play. Go aggressive bro!!! You will thank yourself later....

I'm defiantly going 4.30's when my time comes, I'm just working on suspension and handling mods to prepare for the jump
