Re: Harmonic balancer

Depends on what crank your running, if it's internal/external balance from the manufacturer. I'm assuming it's a gm crank, I believe the 1 piece uses a internal balance balancer and a external balance flywheel. If your not sure take the rotating assembly to a machine shop. Might not hurt to have it checked out, and they can let you know what you need.
