No, I didn't notice the round bit of metal in the first or second photos. The journal oil galleries look open and clear to me. Although I do see some smearing of bearing material around the oil gallery aperture. See zoom of your photo below. If the spun bearing(s) failure happened at high RPM - say ~8000+RPM, then the event was possibly too sudden for oil pressure to drop and a check engine light to trigger. I'm interested to know what your repair strategy might be. New stroker from Carbahn perhaps or something else? IF the main bearings also failed (or failed first) then the block saddle(s) might be cracked. Take a good look at the mains and the block saddles.
