Can anyone tell me what the Thunderstorm piston ring material is - iron or chrome-moly? A shop that I'm having hone the cylinders feels that the material affects the finish they would put on the cylinder. |

Roger: Suggest touching base with Pammy or Al. If you can't get what you need, drop me a note. |

Thanks. I usually shy away from asking questions at a business when I'm not planning on sending any $$ their way in the short term. I talked to both, both suggested further contact points. In the end, Dan at NRHS gave me what I think the shop really wanted -- hone to a 280 grit/finish. (I'm sure I've butchered something there...). |

Iron rings are fine, but moly is a better material due to its porous nature. It will hold oil a bit better due to this, but both materials are suitable. The thing you should probably steer clear of are chrome rings as they are designed for engines run in very dusty environments. |
