I have this pair of ORANGE torque converters for 727 and am hoping someone out there knows something about the stall speeds. One has "492" written on it while the other has "692". They are also stamped with the same numbers. The "492" also has a "high stall" sticker and is neutral balance while the other has an illegible sticker and is for a 360. I realize that the stall speed is dependent on engine output but gimme what you can. Any help appreciated.
