I have searched the archives and found some information and wanted to confirm.........
I believe that the harmonic balancer assembly for the '67 Big Block (435 Hp) is #3863108. I also understand that this "assembly" is still available from GM.
Questions:
1) Is there any difference between the one being sold now and the assembly that was installed in '67?
2) I have seen NOS ones and, (I'm not sure of this) original ones with the number 3870325 cast in the hub section. I believe that Joe L. noted in one of his replies that this was just a casting # for the hub. Is there anywhere on the assembly that the 3863108 assembly # appears?
3) What should I look for as far as identifying marks on an "original " balancer? I understand that they're 8" in diameter and 1 & 3/4" thick.
Thanks for your help
