So I'm a three strikes rule kind of guy. Counting me, you now have three people suggesting you privately ask this person to make this right, or publicly flush out this potential Hall of Shame candidate. It's pretty simple: whether I knew it or not, if I sold you something as forked up as that engine appears to be judging by the pics you've shared, I would refund your money, or expect to suffer the public shaming. If my kid doesn't live up to a reasonable promise, I expect the other kids in the neighborhood to call him a liar. Those are the rules of the playground, and they continue on later in life.
Good luck with your truck. It looks like really nice rig and I feel for you as you really just wanted a drop in used engine, not another core that needs everything and sets your time/wallet back to almost square one.
