Harmonic Damper
 

I am currently putting together the engine listed in my signature, I still need to purchase a harmonic damper, Any suggestions would be helpful. Thank you.

I am running a Romac with the alloy outer ring (lightweight) and love it. Very nice piece. It has a steel inner hub with an elastomer bond to the outer ring.

Make sure you get the correct balance to match your engine.

Have also heard good things about the new Powerbonds...basically the same design although I'm not sure they have a lightweight outer ring option.

Fluidampr on my 331.

Get a SFI approved balancer, at least.

I would say an ATI, Powerbond, Romac or the TCI rattler. But I do favor the ATI unit because it has an awsome reputation in the race car field.
my 2 cents.
