There's a new project update for you this morning. GRM advertising sales ninja Steve C. is making some more progress with his sick Camaro.
If you're into post-failure analysis of engine parts, you'll definitely want to check it out.

looks like a bunch of needles/needle bearing shell came apart
Yup wheel bearing shell came apart.. I'm fairly certain that the tie bar snapped at 6800 rpm. That's the part that keeps each I/E roller lifter pair from rotating in its bore. Once a lifter rotates, it ceases to roll. 20% of the roller wheel had worn away. Then the wheel failed. A lot.
That tie bar looks like a real weak point in the design of the roller lifter.

there are thousands of engines out there with aftermarket roller lifters with tie bars that run for a long time without any problems. but like anything else mechanical, failures do happen.
Agreed. No complaints here. That lifter survived seven years of 6800 rpm without so much as a whimper.
Poor little lifter.
didn't know they used wheel bearings in engines.
