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.

Good points, you could argue that the LS motors just by virtue of being newer are going to have a better shot in used condition. There is also that oils are way better now, so they got that benefit during their life.
