Whichever one you feel better suits your driving habits. You'll get eleventy billion opinions, none will be right, none will be wrong. I don't think there is a more beaten to death topic on Mustangs than this one besides the "what will it make on the dyno" lol.

That sounds about right from what I've heard. Well the car won't be going to the track (at least not anytime soon lol) but I need it to be street able and still smooth.

Streetable is all in what you feel is streetable. Dudes roll around with stalled automatics and 4.56 rear gears and feel it is perfectly streetable. Others drive the highway a lot and don't want to be whirring down the road at 2800rpm in 5th so lower gears are better for them. Its all in your habits and what you want to do.

I run 3:73s and love them. It works great as well for freeway driving.

Low gearing = High Number
Vice Versa with high gearing

The higher the number the taller the gears and the quicker you will accelerate.
The lower number the shorter the gear and the slower you will accelerate, but you will be at a higher speed before you redline. It's all about finding the balance between how much power you have and how fast you want to accelerate. If you have a ton of power and really low gearing you will blast through the gears and reach top speed very quickly.

Well the search button does wonders for answering questions like this and then there's also a good thread in the stickies section showing what it's like driving around with 4.10s... I would start there and then ask whatever questions that weren't answered in those various threads.

Soccerluvr, you got it backwards.
In a nutshell, it basically relates to how long it takes to get through the rpm band... taller gears are smaller in numeric order (like the stock 3.23s), while shorter gears are larger in numberic order (like 4.10s). The bigger the number, the shorter the gear, and the shorter amount of time it takes to get through the rpms.
Think of it as trading weight for distance. An amount of energy that can move one pound one foot can also be used to move two pounds six inches or half a pound 2 feet. The gear you choose determines what kind of work you are going to get done with your foot/pound of energy. A short gear, like first, will move a lot of weight a short distance. A tall gear like fifth will move a little bit of weight a long distance.

That makes a lot more sense now. I don't really plan on doing anything like a supercharger to this car (that's the next one with a coyote engine lol) so maybe I'll go higher on the gears. I'll watch some vids and get a good idea on what I should get. Thanks guys!
