    I have gen 6 502 and the balancer has 2 marks there is a lot of paint on it and I cant see the numbers on it. now looking at the front of the engine, the engine rotates clockwise and the balancer has has 2 lines on it. Is the first mark TDC ? What is the second mark?

    Can you buy a harmonic dampener , I would guess of steel versus cast construction and at least 1/4 key way that allows solid driveline adapter to bolt up to. Must be available since there alot of PS Ks running this solid driveline and I would hope that they run harmonics.
