Factory High Stall converter
Probably somewhere between 1800-2000 rpm. From the factory, unless there was a high stall listed in a Mopar performance catalog, the converter the 360 had behind it (in all applications-truck/car was a 12" unit that was classed as a medium stall. It had a narrow ring gear and two small weights added to the back of it(ring gear side). To this best of my knowledge this was the only converter for the 360/727 non-lockup style transmission.
