Ignore my post. My mistake this won't work since the engine is internally balanced and the harmonic balancer is externally balanced. bt
I am building a mild Pontiac 455 probably 400 hp and 440 lb ft of torque. It's a not a race engine. Searching for a harmonic balancer I found this one and wanted to ask if you have heard of any reliability problems with it?
