Harmonic Balancer ID Needed
I need a balancer for my '61 FI. I need to know what the below balancer is off of. I do not have any numbers from it. Anyone know what it is off of or what it fits? Thanks

The 1961 FI harmonic Balancer is #3764318 is 6 1/8'' DIA. The one you are showing looks like a 283 & low horse power 327 replacement.
The GM #3764318 is a two step balancer that was used for the following;
1959-61 with Duntov cam, both Corvette and passenger
1959-61 348 cid with 3X2
1961 409
