Default how to determine the stall of a converter?

Is there a way to tell what kind of stall a car has? for example lets say my car has the st3500 and I bought the car withough knowing it had it. how would I know what stall speed it had? is there a simple way of checking??

check out www.converter.cc its not thee most accurate way but they have a basic overview...it really depends on the power of the engine, the tires your running and how good your breaking system is...the same stall might stall higher in another car. Bottome line is theres no full proof way.

The rated stall speed will always be higher than what you
can "foot-stall" to. If you put the e-brake and foot brake
on hard, and give it some gas, the true / rated stall will
be a few hudred RPM higher than what you see on the
tach (seemed like my stocker would go to about 1500
and rated 1800, my TCI SF will go to about 2400 with a
rated 3000RPM stall speed. Once the brakes can't hold it
you know you're getting up on the stall torque multiply
slope, but the brakes won't hold all the way to the top.

So rule of thumb might be whatever you can get on the
tach, and add 500RPM (ish). Maybe it's more like a
percentage, I dunno. But you get the idea.

You can measure it at the track with autotap or EFIlive if you don't spin by logging engine rpm and mph (or output shaft rpm)
