Generally speaking "low stall" means the converter is tighter, the blade angle is higher, resulting in a lower initial rpm when the vehicle is still and the engine is trying to move it. Low stall gets you better mileage (in these days of lockup converters this is less an issue) and less heat which is loss.

You want to use low stall if you can but when the load is heavy and the engine low in torque the factory used a high stall to get the engine rpm up to give acceptable off the line performance. So (roughly) 454's and diesels got low stall in most cases. If you got say a 350 in a 3/4 ton you got the high stall. If you got the small V8 or (God forbid) the V6 in any thing it where it was an option you got the high stall.

Oh. And the sticker is on the converter.
