We had SM Lifters (not Schubecks), a puck got scared of 9K+ rpms and decided to leave, did a fair bit of damage. This was at a pro's shop being dynoed when it occurred.
Rights springs, right everything, lifter just flat out failed. Cost a bunch to fix it all....

Wow 9K+ rpm for a flat tappet cam and lifters. What kind of spring being used for that application. Just want to know that combo.

I was at a dyno session with a new 426 max wedge. 5th or 6th pull there was a quick miss in the engine and immediately the engine was shut off. Completely destroyed the new maxie. Needed new pistons and a complete rebuild. A puck had come off one of the new lifters. I would not use them, but many racers have had good luck with them. Good luck to you! Dyno
