Re: 478 pistons
The only other pistons I've seen with two expansion bands are Badger brand pistons, got a set of these for 351E I have. It does make you wonder what other piston manufacturers were up to as far as GMC V6 pistons are concerned. Piston scuffing has been an issue with the GMC V6 and aftermarket pistons but I do feel I can trust the Badger pistons.
