Stock high stall converter stall? 5.9 magnum

What's the stall on that convertor mderoy? Mine flashes to 3500. I highway and freeway drive it often with my GVOD.
With my 360 Magnum I was told by Paul (Turbo Action) 3200-3400. Car drove like Grandma's sedan until you hit the pedal. Normal 60' was 1.64 launching at 2000 rpm.
