Material came from the bearings. The crank was scored pretty bad and needed to be turned. I caught it in time to save the need for more boring. The only damage really was to the crankshaft. The oil pump was still in good shape as well as the bronze bushing on the distributor shaft.
One rod bearing had bad wear on it also so I had the machine shop balance the engine again to be safe and it turns out the “reputable shop” i used the first time didn’t do a good job.
