I dunno bud, I've seen several boosted 302's (different application I know) making well over 500HP to the tires on boost running Castrol Syntec 5w-50, M1 5w-50.....etc with zero wear on tear-down and going well beyond the mileage you've cited. And neither of those oils have the same list of OEM endorsements as M1 0w-40.
I've also got a fair bit of experience with heavily beat on N/A 302's with M1 0w-40 including my own 338,000Km example that have shown zero wear on tear-down, and those tear-downs were performed for performance upgrades, not due to issues with the engines. Not quite in the same league as what you are alluding to, but anecdotes are anecdotes
