What exactly is a stall used for??
What exactly is a stall used for?? I have had my car for about a month and a half and i have noticed that to get the full use of a cam you need a bigger stall, what is that for exactly??
Doesnt the stall just allow the driver to have higher RPMs when holding the break for launching purposes, or is there another function of the stall.

The proper stall converter will allow the engine to stay in the cam's power range, this will result in quicker acceleration from any speed vs. the stock unit. The stock converter will not allow you to use the power curve of your new at lower speeds, only after the rpms are high enough for the cam's designed range. Does that help you understand the need for a bigger stall?

purpose of a larger stall: towing 
a stall converter does many great (and UNgreat) things for our automatic transmission equipped vehicles. torque multiplication is the biggie with stalls, i think. by multiplying the tq and IMMEDIEATELY achieving the car's powerband, you can launch like no other. even after a launch, the stall is still working and multiplying tq, etc, but this action only takes place within the stall speed. larger stall converters also offer what's known as shift extension, in a nutshell: your rpms don't drop back as far after an upshift, resulting in the engine not bogging down and constantly being within the powerband. a stall will improve any car, regardless of its modifications.
the downside to a larger stall...you will need a transmission cooler, as having the converter slip, or stall often will create a lot more heat. if your transmission has torque management active, a stall will cause it to work more. a stall will soften your shifts, on a stock tranny, almost to the point you can't even feel the car shift. it will lower in-town mileage. it will make getting traction a total BITCH!
my thoughts: i will never have another automatic vehicle that does not have some sort of stall converter, be it small or large.

Only if you get on it will it affect traction. If you are getting into racing you will want a sticker tire anyways. It won't make your vehicle undrivable on the street unless you are pushing some serious engine mods that have already significantly diminished the drivibility.
Plus no drops of MPG on the highway. In the city, only if you get on it. I drove a 3500 stall car for years and didn't complain. Once you drive a stall car you will NEVER own another vehicle without one!
One last piece of advice:
DON'T CHEAP OUT ON THE CONVERTER!!! If one brand is 100 dollars less then it is probably a lot worse as far as quality goes. You get what you pay for and its your car. Get the best! Go with a name brand that has a rep and not some recently started company. NEVER be afraid to ask which to buy, but don't take one person's word on it.
If you are going to change converters now is the time to change your rear gears also as that mod has a influence on which converter you will want.
Plan ahead. If you are going to add nitrous, cam or head work, anything. Tell the converter manufacturer ahead of time and buy a converter for that as mods will effect the converter stall.

Technically it's called a torque converter. Your stock TC has a "stall" speed to as they all do, though it is only ~1800rpm.
Sorry I just get annoyed by people who constantly call it a "stall".
