Usually, balancers have an enertia ring held on by a rubber elastomer, and this is the part that can fail and allow the outer ring to move, making the timing mark usless. Some motors only come with a single piece Hub. Which do you have?

Besides the cam, what other parts did you add or change? (pistons, exhaust, head work)
What do your spark plugs look like? Should have a light tan coating on the porcelin insulator. White is too lean, darker than tan is too rich, metal flakes stuck to the porcelin mean detonation
Did you replace the valve springs?
