440 Harmonic Balancer Timing Marks Off

it's probably because you skipped one of the first steps in degreeing the cam. That is, checking TDC on the dampener. Once you confirm that the TDC mark is correct, you match mark the inner hub of the dampener and the outer ring of the dampener, so you'll know if the outer ring spins subsequently.

Thanks for the reply back. I guess I may be confused. According to my edelbrock kit there was no need in degreeing the cam bc it was as close as possible according to the paperwork from them And if you set the chain up how you need to with the mark alinged then the cam nipple is only going to sit one way in realtionship to the sprocket which in turn angles the crankshaft/sprocket one way... are you trying to say that i would have found out if the outer ring has slipped in the past?
