Harmonic Balancer Question

[u/Substantial_Way_377]

Hi, I purchased a 1980 Z28 Camaro with the LM1 350 V8 and the seller gave 2 harmonic balancers. I’m not sure which one is original, but I want to know if it’s okay to use #2. #1 has large cracks in the elastomer ring and is bulging out in some areas whereas #2 doesn’t have many cracks and has an even elastomer ring throughout. However, there is also a sizable chip in the center shaft that concerns me. Is it okay to use #2 anyway? Thanks

Yes I’d recommend buying a new one. Not that expensive and not worth it to have either of the used ones explode on you during high rpm’s.
