Motor won’t turn over – any suggestions?

Grant - thanks for the link to the video.

Here's where I'm at.
Took the cams out and found scoring in the journals. Looking at the valve train - nothing appears out of the ordinary.

My assumption, due to the scored cams on both banks and with the engine still locked up, this will cost too much in parts and machine work.

So I bought a used engine with a LN retrofit bearing, and am waiting for the AOS to arrive. Will install a new clutch + and then hopefully it will run.

I would like to further investigate why this motor failed, but with lack of space - I will rip into it at another time.

Here's a pic of the cam journals.

I had cam journal scoring on an engine... it is discussed here.
