wobbly harmonic balancer

[crm318]

i currently built a 350 and started it for the first time yesterday. it ran like crap. i assumed it was because the timing was way off and i need to break in the cam. today. i tried to let it idle, but it ran rough and i heard i slight rattling/knocking. when i was putting the timing light on it i noticed that the harmonic balancer was wobbling and almost hitting the power steering pump bracket. i took a closer look and the inner part was perfeclty centered and the outter part was the part wobbling. also it looked like the pully was slightly off to. do you think that the 15 min of 2000-2500 rpm cam break in could have messed up my engine? the timing mark didnt even show up on the balancer with the light on it. what do yall think? and yes, i will getting a new balancer.
