Default Stall Speed ??? Help

Hi I am wondering what my stall speed of my torque converter is. I have a 95 firebird lt1 4l60e. I looked at the converter and there is:

autotrans Part number 77-29 HP
K1 E 55C
2 C 488
7's stamped all around

Thats all things i can see on it to identify anything maybe. I tried to look for a autotrans company but no luck. Thanks for any help

That should be a 298mm style converter. The #7 stamping could be anywhere from a 2000-2500 stall, depends on the stator. Sorry, not much more help than that....
