Bent a lifter?
This leads me to believe the failure had nothing to do with bouncing of the RPM limiter, but rather chance. Mechanical things to fail, sometimes for no discernible reason.
In 30 years of track life in one form or another, personally bouncing off the limit more times than I can count and I have only personally witnessed one failure.

Follow the above advice at your own risk lol. I saw a guy at Thunder Hill bounce off the limiter in 3rd gear every lap for a good hundred yards as he was to lazy to shift to 4th. He was under the impression it was fine. 3rd session he came in with a clanking so bad we all assumed the worst. Turns out he got lucky and only bent a single (lifter) pushrod. This was a stock LT1. So while you can get away with touching your redline, extended use has huge risk as It’s a safety gap not a tool. Your valve train is moving very fast and it’s not a good idea to keep accelerating to the limit, cut all power, then instantly accelerate to the limit and repeat, with lots of heat, and under extreme load. It’s fine to touch it but it’s definitely not meant to be used if you don’t have to. I try to avoid it at all cost as it means I messed up and made a mistake. Just like missing an apex, every thing needs to flow perfect. Killing drive sucks, killing your valve train sucks even more.
