I have a 2004 Stang and am wanting to do gears. But I can't decide on which. The car is a manual, and I don't know if I should go with 3.73s or 4.10s. Any suggestions?

I'm not saying that you can't do a lot of highway driving with 4.10's it's just that if you do, your adding a lot of extra engine wear, kinda like me driving in 4th gear [ well, not quite] I'm getting 24-25 mpg [30-31 imperial gallon] with the stock 3.27's,Joel's98GT said:I drive 80 miles a day, all highway on my car, it has 115k miles on stock longblock and gets 21-22 mpg highway.
all this and my non-headswapped car would most likely beat you at the track (as long as you aren't spraying )

Now if you cann't decide between the 2 get some 3.90's.
