8” Big Block Chevy Harmonic Balancer 3870325
 

I have a really nice big block Chevy 8” harmonic balancer for sale. This is correct for all 396/402/427 high performance engines.

The casting number is 3870325 and it’s dated A9F. From all the research I’ve done, I believe this was built January of 1969.

It isn’t hammered on too bad and the rubber looks good. This is correct for all BBC internally balanced, high performance BBC engines.

$150 plus shipping if needed

Thanks for the ad, Kurt
