Hi all from Perth W.A., I have not posted a question for a while although I have spent many hours sifting through posts about 340 builds and pistons and rings and more...
I am collecting parts for the build of a 1971 340 - it's all machined up ready for assembly (although the cast 1.88" int. heads might yet get some port work). I have a set of new KB Hypers 107 (0.070 over) to suit the block's 30 over rebore. But now looking for rings. I want a step up from the OEM cast type rings but it's not a high budget race engine so the in-between I guess are moly rings. Need to be 5/64, 5/64 and 3/16 for the oil control rings
Many of you guys have decades of experience in Mopar engine building...so my question is: As with many other things in life, is it a case of "you get what you pay for" with rings? Or does the name have a lot to do with the price ... Hastings rings prices are all over the place - even for their Premium Moly range. How do Speedpro Moly rings for $85 compare in quality to Total Seal at $116 ? Speed Pro are Sealed Power which are a Federal Mogul company. Then there is Summit Racing, some of their ring sets are not cheap - are they all made in China? I looked at Mahle Original ring sets but for this size bore, their second ring is different to their top ring, Weird! (5/64 and 3/32). Perfect Circle are same as Mahle I think. Then there's Howards, Ross etc
Are these companies all making their own rings or do they all buy generic rings from a couple of manufacturers and put them in their own box with their own advertising?
Also is "Plasma Moly" and just "Moly" the same thing, or is Plasma Moly better?
Lots of questions (maybe too many for one post!?!), hoping for some guys who have knowledge and had experience with different brands of Moly ring sets for the common KB Hypereutectics.
Thanks.
