You need to upgrade axles also. You didn't give us enough info to determine what gear you should run.

If your car is a manual and a daily driver I wouldn't go any steeper than 373s. You will still be able to drive on the highway.

get 3.73's from ford racing....gives the car a good kick in the pants and you won't be screamin on the highway like you would if you got 4.10's

You guys are all wrong 2.73's the best by far. You can cruise along at 100 @ 2000 rpm
