I got a blown up 5.7 for free and rebuilt it, collected a bunch of parts for it and there it sits. I wanted carbureted and have a couple intakes and so on. Nothing happened.
Plan B was, I've got two vehicles with 5.7s of the same vintage, one of them is my truck with 250,000 miles on it. It's really not worn out enough to change it. If I ever sold that other engine sitting there, the truck would probably throw a rod through the block the same day.
