Double Moly Rings
Back in the day (60s/70s) we would use double moly rings on both SBC and BBC -- now it seems they are non-existant. Ring sets now for high perf street and some weekend race engines lean toward the moly top compression ring and a cast iron second ring -- oil ring pretty much remained unchanged it seems. TRW/RAMCO, Perfect-Circle, etc. were the manufactures that offered the double moly sets.
Do any of the "expert engine builders" here know where I can get double moly or do the single moly ring sets work just as good?
Thanks -- TAZ
