I just pulled the balancer and compared it with the old one. Of course one is a 50oz and the other is 28oz but that doesn't mean anything when comparing the timing marks to make sure the new one didin't spin a little. I stacked the old one on top of the new one and lined the key way slots up. As you can see in the photos the timing marks are dead on so it doesn't look like it spun. So hopefully it is just not balanced correctly or the flywheel isn't. If they are both good then the engine has to come back out and I have to take the rotating assembly back down to CHP to be rebalanced. If that happens I'm going to be pissed!
