All converters are 'stall' converters - the difference is whether they stall at stock speed (roughly 1500RPM) or higher.

More or less, the stall speed is where a torque converter really 'bites'. You only need to worry about it if you're running a hot engine that doesn't have a whole lot of bottom end, or doesn't like to idle much. A stock converter, you'll generally have a hard time holding the vehicle still if you try to get the RPMs above 1500 or so...the higher 'stall' a converter is advertised with, the higher RPM you can do before it'll really try to move.

More or less...it's how guys with autos launch a vehicle at anything higher than 1800RPM.
