I'm getting ready to pull the trigger on a 470 rotating assembly for a 400 as well. I saw the indy kit at MATS and was thinking it would be a great kit. Can Bob George or another Indy dealer clear up the confusion about the counterweights? I was assuming it is a drop in kit that would need final balancing. Why would they sell a kit for a 400 that needed the counterweights turned down?
