Moly rings eh? That's new to me, wow, the 340 really was special then. Maybe they upped the nickel content on the 340 castings if they knew that many of them had a good chance of being raced. While I'm here, do you know if they did anything to the oil pump? All I have heard is that it was "revised", whatever that means. They couldn't really make it a HV pump as that oil pan was pretty low at 4 quarts. For the high revs it was capable of I was a bit disappointed they didn't do more with the oiling system, such as Ford did with theirs.
