Life is never as black and white as we'd all hope. Lol.
I'm fortunate to have trucks available to me to use while I figure out how I'm going to resurrect the v10 truck.
I've moved on from the two engines I mentioned.
Shop that diagnosed the truck quoted me $6 grand on a 141k mile engine swapped in. Bit too steep for me right now.
I'm finding graded A used engines for 1500 to 2000 with a little warranty. 80 to 140k miles. Another $1000 in parts and party favors...I think I can swap it with a bit of help. No better time than right now to do my first swap. I trust my work more than most anyways.
@kenny thomas I will look for a motor for your yota too.
