As far as vibrations and harmonics effecting chains goes, Pontiac had to come out with a better chain for the 195" 4cyl. which was 1/2 of a 389 due to the vibrations of that engine. The links had a wave type of a flat spring between the links and they would last. They were the chain to use in a Pontiac before the roller chains came out. If anyone on here knows of any GM# 9772801 chains or the version Republic Gear made, please let me know. John Kissel K242
