Please me some torque on converters

1968 and up 904's behind either the leaning tower of power or the 318 used two converters, one classed as a high stall and the other a low stall. The factory placed decals on the side of the converter, the low stall had a triangular decal that said "lo stall", and the high stall had a round decal that said "high stall". There are various opinions as to what stall these things are: the low stall around 2000 rpm and the high stall around 2300 rpm. Depending on who you talk to these stall speeds can/will vary. There are NO weights added to these converters as TrailBeast explained, and if there are any weights welded to the front(engine side) of the converter, somebody has added these weights for whatever reason.
There is a way to tell if the converter is a low or high stall even if the decal is missing. Chrysler in their wisdom stamped a code on the hub side of the converter. It is a 3 number code. Not at times easy to see, but worth while looking for. If you find this number, I might be able to help you further. Also, the converters from the photos look like they have been rebuilt in the past at some time, so there might be either a painted or stenciled part number on it. Most if not all converter rebuilders will put their own part number on it. The shop I worked for in the past would have stenciled part number 762 on it before putting the converter in stock.
Make sure before you chuck one of these in (they look used to me), that any oil inside is pink, with no debris in the oil, and that the hub that goes into the pump is as smooth as a babys bottom. If the hub shows any sign of wear (run a finger nail down it) it'll leak and could cause the pump bushing and front seal to fail. Also, look very closely for any sign of cracks in the hub were the pump lugs fit into. Most converter rebuilders will automatically replace the hubs on Chrysler converters for this problem.
Used converters IMHO make great door stops.
