It is more of a low RPM vibration, and I still have it with the fan belt removed and car in neutral. Not noticeable above 40 mph on the highway. It doesn't seem to be a telescoping vibration due to an exhaust clearance or of that nature.
do it look like the balancer is wobbling at idle with the belts off ?
was the motor rebuilt ?

The balancer doesn't appear to wobble. Yes the motor was rebuilt by a previous owner approx 2500 miles on it. I was told it has a 6 pack cam, bored just 20 over, and the vibration was noticeable when I bought it. I wasn't given much info on the rebuild itself. I realize it is hard to diagnose these issues without having the car in front of you, so I appreciate all your efforts.
It could be almost anything , unless the balancer is out of balance putting on another one will not do anything , same goes for the flywheel , you are also assuming whoever rebuilt it balanced it correctly .
But that said I had a vibration in my car that turned out to be the flywheel . I was putting in a new clutch and had it resurfaced and my engine shop said it had been cut on an angle previously , was .020 thinner on one side , he made it flat and rebalanced it as it was off .
