Torque converter stall speed

Hello All,

Pulled motor and transmission from the 74 Duster and found that it had a 78/79 727 transmission with a lockup converter. I'm trying to determine the estimated stall of the converter and not coming up with much. The converter has a CVC or Recon P/N: C24LUHS and everything I've read or found only refers to it as a High Stall but does not provide any ranges. Does anyone have any idea what High Stall may refer to in terms of a stall range? This P/N cross references to several other Mfr's and they all pretty much say the same thing. Generally there are 2 P/N for each application and 1 is referred to as Low Stall and the other being High Stall. Maybe someone here has info on this.
