The BB kit Matt got and installed onto my 660 is still going,i only mill with it and so far so good.I would not say power wise it is any better or worse than the OEM one but it sounds differant.
There is no way i would put a BB kit on a new 660 if you are looking for power,only a port job you will find that.:msp_smile:
