Been looking for a manufacturer that makes moly piston ring sets for my 324 build. Engine bored 40 over for clean up. All I can find is cast or chromed sets. Just another thing holding me up.

 

Ross Racing- check 'em out

 

After some internet work I found that Hastings #2M660 piston rings will fit the 324.

 

Just curious, why the moly rings ?Do you find them to be better in some respect? I have never used them and am just carious what the advantages are....Tedd

 

I met a guy in my area that used to work in the Oldsmobile plant in the mid west that put these 50's cars together. He is engine machinist/ engine builder of Mopar engines but still has a soft spot for the Olds engines. His experience with cast rings are that they wear the cylinders more than the moly rings even though the break-in is about the same. He convinced me to precision balance the engine parts as well as the Torus cover off of the transmission. He has built these engines for performance and racing and shares things but does not try to push them down my throat.
