LU converter Question

[Whitey]

Do these Lock up converters have different stalls? I have a 727 with a 2300 stall converter but going to a 518 but this has a lock up that I have to wire for. Do all manufactures make these converters?
Thanks...

Not sure but I know the converter in my diesel sure seems to be pretty loose until it locks up.
