I have a set of very good used custom JE forged 4.1 stroker pistons made for 1/16" compression rings and 3/16" oil rings. A ring package does not exist for a 3.995 bore in that ring width. I used 4" JE file fit ductile iron rings (.005 larger) in the past because JE said they would work, and they did for a long time, but I experienced excessive cylinder wear and eventually excessive blow by. If only I knew then that I should have gone with a 4" bore. My thought is to use standard Speed Pro or Sealed Power moly rings for a 4" bore and file fit them for another block I can have bored to 3.995. Does anyone think this will not work?
