I would feel at least marginally confident just re-ringing a used LS block. Maybe bearings. But otherwise all OEM parts. I wouldn't feel the same about a junkyard 400. You are always gambling with used parts, but I think the gamble is way less with a newer motor.

Correct. Agree and to take that further, this is where that thinking is flawed. Where are people going to find a 60 year old used 400 that's in good enough shape to do the things people are doing to current used LS engines??? You just aren't. Doesn't happen these days.
The whole reason LS engines are being bought and retrofitted is because they aren't that old, low mile examples are everywhere, and it's cheap and simple to buy and plunk in, add a few performance parts and you're on your way. That doesn't happen anymore on a production engine that's been out of production for the last 40 years people, lol.
