Factory 12" converter with for 19 spline shaft - any idea what stall speed?

The title basically says it all, I'm looking at a factory 19 spline 12 inch converter but I have no idea what the stall speed would be - any ideas? Thanks

Depends on what engine it's behind. The more torque the engine produces, generally it makes the stall climb. But I would say it'll be pretty low...high teens maybe behind a big block.
