Harmonic balancer for '70 454

[Steve G.]

Am finishing up engine rebuild. Harmonic balancer rubber is cracked / brittle. I am looking for least expensive solution that will function properly and look correct. Does anyone recommend rebuild vs buy new? If new, is GM replacement (not sure if they even have a replacement) any better or worse than calling local parts store? thanks, Steve

Steve------

There are quite a few options for a new balancer:

GM #10216339------about $250, GM list

NAPA #BK6005209----about $75

Dorman #594010------about $50

The NAPA and Dorman pieces might be Chinese-manufactured, but that does not necessarily make them bad.

I think that any of the above will, once installed on the engine, be pretty much undetectable from original.

I don't know what a rebuild would cost for yours. Contact The Damper Dudes or Damper Doc, both located in northern California (Redding or thereabouts, I think).

Thank you Joe! Given that info, I will buy an aftermarket - probably via Napa as there is one local to me. I'll store away my original in a box... Steve
