Balancer slides in on install

....and speaking about the Pontiac remarks, I've personally torn down probably four Pontiac V8 engines and they all had press fit balancers. For whatever that's worth.
My Dad and Brother built a pretty stout 488" stroker Pontiac for my brothers 71 Lemans a few years back, going to see if they remember what the balancer was like going off and the new one going on just for curiosity sake.
