Used C3OE Harmonic Balancer

Here is an Ebay auction for a used C3OE Hipo harmonic balancer by Ebay member "mgunner" with a Buy-It-Now of $595.00 or make offer:

This is an original early high performance 289 balancer. It will work on Amy hipo 289 engine from 1963-1967. This is unmodified as far as I can tell. There are a few dings in the back edge probably from removal at some point . Still looks very presentable. This was the OEM balancer used on K code engines
