360 balance ?s

. Update.. I decided to bring #1 up to tdc I pulled the plug. Got it as close as i could to the top bumping it. And the damper timing mark was where it should have been so no slipping on the damper.I noticed my distributor was leaking oil, so i pulled it out. Replaced th o ring and gasket. Put it backtogether And fired it up to check the timing. And while watching it run from inside i found the problem. Damn fan clutch. The bearing went bad and it shifted to one side. I shot over to the parts store, picked one up and put it in... No more shaking!!
