it depends on what trans. you have in it first. If you have an automatic you would be better with 4.11's. If you have a stick shift the 3.73's may work better depending on your mods and tires (slicks, drag radials, street) 4.11's should work better as long as you can hook up. The top speed will be affected. I have 3.73's and a 5 speed and with the stock gears (2.73's) I figured the top speed with a redline of 6K rpms somewhere around 200mph, I don't remember exactly. With the 3.73's it is closer to 150mph. That is of course if you got a big and bad enough engine to pull 6K rpms with 2.73's.
