Oh wow, it looks like you have a lot going on in there.
When I had my engine rebuilt the shop must of left some debris in an oiler or installed too tight of rod bearings and clogged up. It took out the first bearing to not receive oil, #1. Bearing lost its coating onto the crank. Good thing I had a doner engine with a perfect crank. I did the measuring for the repair and replaced with racing rod bearings with a closer matched set so it got a better lubrication. If you want it done right, you got to do it yourself. I questioned their work because the bearing locked onto the crank at 25mph, so it definitely was something left in an oiler or missed measuring specifications and clogged. It's ran perfect ever since I fixed their work, lol.
