I'm normally in the GX470 forum, but I came across this and had to share.
The guy apparently runs a parts yard and got this bad motor in from an LS460.
What went wrong? Hint: oil pan is full of sparkles.

Watched this earlier. Unless a fluke I'd say severe neglect doomed that engine, or physical damage that caused oil starvation.

 

There aren't any holes in the block, and the inside seems really dry to me. I think an oil change place forgot to add oil.
