Realoem has identical part numbers of a 330 vibration damper and a 320 one. Does this imply that an ATI damper made for a 330 would properly work on a 320?
Indeed it would

edit: I also asked Ricky if there a minimum power level that the ATI damper would be designed for. He said, "The 5.5" OEM accessories damper is good for anything up to about 500-550HP."
