Symetrical harmonic balancer is on the internally balanced engine. The externally balanced engine uses a harmonic balancer that has kind of a cam lobe shaped counter-weight on the front of it. The internally vs externally balanced small blocks (LA series) also use different flywheels or flexplates. I would think the same is true on the big blocks. Someone correct me if I'm wrong.
