I'm pretty sure the higher the number the more power the engine makes. So an 8v engine makes more power than a 4v engine and so on, Correct me if I'm wrong. There's more to it but I can't remember, I read it on another thread haha

More valves generally ( again generally ) mean better volumetric efficiency ...
The better the VE, the more powerful and efficient the engine is. Hence why the new coyote makes so much power and yet still gets good gas mileage.

3v's are generally faster in stock, factory form.

Sound is up to the owner...

...what the difference was between the 2v and 3v ...

The "v" refers to valves per cylinder. Thus a 3-valve engine would allow for better breathing and fuel mixture flow. which results in more power. In a 2v there are 1 intake and 1 exhaust valve. The 3v uses 2 intakes and 1 exhaust valve. The 4v uses 2 intakes and 2 exhaust valves. The 1994-2004 (with exception of Cobras and Mach Is) had the 4.6L 2v engines while the 2005-2010 had the 4.6L 3v engines. Starting in 2011 the engines went to 5.0L 4v. Hope that helps.

Besides the fact that one is a 2V and the other is a 3V, there isn't too much differnce. The 3V has an extra intake valve and a better intake manifold for increased flow which accounts for the power increase over the 2V. The 2V engines were cast iron and the 3V engines are all aluminum shaving about 70lbs off of the front of the car.

This. And except for the motor mounts, the 2v and 3v blocks are the same.
