There is no set stall speed for any given converter, the more power you feed it the higher the stall speed will be...IOW, the same converter behind a 413 will stall higher than behind a 318.

Location: Branson, MO		Torque converters have ratings as to their stall speed. 1800 rpm’s are common for MoPar factory installed units. Racing units are rated around 3500 rpm’s.

Interesting question, all I can add is that the powerflite converter is said to have an aprox 300rpm higher stall speed than the torqueflite  converter..... I plan to try this out for my next build.  It does appear to be smaller in diameter.
