Quick video of a 1983 Pontiac Firebird 2.8 'powertrain' with a wobble on the crank pulley. Pulley is NOT bent as it smooths out at some RPM's! Thinking it's a bad harmonic balancer? That's the only pulley with a wobble BTW. Hard to catch with the camera but it's VERY obvious when you're driving the vibration machine! 

Any ideas?

And yes, that old crusty 120hp junker will be pulled for a 350 soon but want to know if this is something fixable for the time being!
