trust me dude if you go from 3.73's to 4.10's you will notice a diffrent, a lot of people say there the same and there not, also a lot of people say you will loose a lot of gas mileage due to having 4.10's but you wont loose more than 2mpg.

But it does also matter what year stang you have. If you have a sn95 (94-98) go with 3.73s, if you have a New Edge (99-04) get the 4.10s. The sn95s dont have enough power to justify the 4.10s, and they also come stock with 2.73s. The new edges have a lot more power and also came from the factory with 3.27s (i think, it might be 3.24s).

We know, we were there. 3.73s are a pretty nice improvement over any current gen stock gear ratio on a sixer. Only the 94-98 have problems with 4.10s as they can cause minor to even serious engine problems for a stock 94-98, 99+ generally have little to no problems with 4.10s. Now don't get the TB as you'll need a bunch of secondary supporting mods to gain any hp out of it, secondly your intake must be port matched for a throttle body to do anything. No you won't notice too much, if any, gain from a cai and pulleys, but if you plan on keeping your engine N/A they are key steping points to future mods. The gears, however, will make a huge improvement over your stock set up. Oh the difference between the I4, V6, and V8 are:
1.) The obvious, displacement, generally, more displacement = more potential power and torque, but this isn't always 100% accurate as there are many common sized engines, such as the 3.5L V6 and the 3.8L V6 where the 3.5L just generates more power.
2.) Firing order. V6s have an even firing order in which the 1/4 pistons fire, then the 2/5, and last the 3/6, in other words there is no unequal airflow. V8s have an uneven fire in which one side of the engine may be firing while the other is in trasition. Have no idea how 4 bangers fire, but it's irrelivant as anyway you look at it they're even fire.
3.) The 3.8L V6 has an ohv set up, in which the cam sits in between the heads, and uses rods that connect to the cam to drive the valves. 4 bangers generally use SOHC or single over head cam where the cam sits directly over the heads. V8s can be OHV, SOHC, DOHC (dual overhead cam in which two cams operate 2-4 valves).
4.) Generally, V6s react better to mods than 4 bangers, and V8s react better to mods than sixers.

I was just reading in another thread that 3.73's are good for any year Mustang. The 4.10's don't do a whole lot more than the other ones. I'll have to find the link and I'll show it to you.
Yea, yea, we know. I had 4.10's in my pony, and I wouldn't go any other way with a N/A 6er.

I didnt see that, so I figured I'd just throw it out there just in case.

I was wondering what kind of cam set-up is in the 3.8 V6's. Crap...that means that I'm gonna have to learn how to work on an OHV set-up. I just came off of working on a DOHC I4 engine. Oh well, I'm up for it.

Yep, although it could be worse, you could have an OHV V8 like me.[:@]
