Why the stall?
I don't get the stall torque converter. Why would you want your camaro to wait until 3200 rpm to come to life? I want mine to open up as soon as I hit the accelerator. Just doesn't make sense...............

Well let me tell you a little about a stall then.
An aftermarket higher stall will raise the point at which your RPMs jump when you nail the throttle. Stock is about 1800, meaning that when you put the pedal to the floor from a stop, you'll go around 1800 and start raising. With a higher stall, it will take more pedal when just driving around town (you'll have to give it more gas to get it going), but this doesn't mean that the car doesn't move until you get to that point. Say you have a stock SS and you add a 3500 stall. When you put it to the floor from a stop, or anytime, it will jump to that 3500 (instead of 1800) and start pulling. Also, you'll have better "shift extension". Instead of your revs falling so far between shift changes, they'll stay right up in your powerband, therefore allowing you to keep pulling hard.
So when you say "I want mine to open up as soon as I hit the accelerator", don't worry, it will! Likely if you're under 25-30 mph, you'll put it to the floor and spin the hell out of the tires for a bit.

The converter is not "digital", all-or-nothing.
I have a 3000RPM stall speed and level cruise
at 30MPH is ~ 1500RPM in 3rd. I can climb hills
at 2000RPM (Florida hills, anyway).
The low-torque, low-pedal coupling "slope"
varies with the stall torque ratio. It is more
abrupt, but further out, with a higher STR.

-if you hammer it and don't have good tires, you're going to blow your street tires off with ease
-Your exhaust will sound louder because you'll be turning more revs
- extra wear and tear on the tranny
-more chance of breaking the rear end if you get a really solid launch

Why would you want to be stuck at a low rpm where it hardly makes any power, and have it drop so many rpm's when shifts? Just doesn't make any sense. A converter will make the car take of SOOOOOOOOOO much stronger and quicker.

The major benefit in daily driving is that the converter keeps the revs up in the torque band, eliminating the "dead spot" after the 1-2 shift where it lugs as you wait for the rpms to spool up and make power. Even at 1/4 throttle with my small 3000 converter, the torque is right there after the 1-2 shift. Very satisfying in every day driving.

Even with drag radials your still gonna spin on the street most of the time. If its a stickier street and you heat em up with a burnout you may hook decently though.
Otherwise if you punch it from a stop your liable to get the 1 to 2 to 1 to 2 shift game - which I'm sure several here are familiar with. You floor it, the tires spin all the way up to redline and it shifts to 2nd - all while the car isn't actually moving all that fast. Then once it hits 2nd it gets traction, the rpms go down and the car "realizes" its rpms are too low under WOT for 2nd gear and it drops down to first gear again and now you probably have traction and it stays in 1st until red and shifts to 2nd again etc. Its a really crappy launch, but a side effect of bad traction and WOT at launch.

It's not too hard to learn enough throttle control to ease it to the floor as traction allows. Immediately start off at about half throttle and increase it until you are at the floor at the top of first gear.
But when I first got the converter I did that all the time!
