Changing crankshaft bearings with the engine in the car.
Cam was fine. So were the crank and rods. Don't know if the condition of the cam bearings had anything to do with the dropped valve, but I suspect they were already bad, I'm thinking from being damaged by some yahoo who installed the cam in one of the two earlier rebuilds. I've never seen cam bearings like this in any of the other engines I've had apart (maybe a dozen or so).
Those look just like the cam bearings in the Hemi Charger Dad gave me (back in 1983) after he dropped a valve and drove it for five miles, embedding the valve head in the piston and knocking a hole in the head.
