I remember working on a vintage Camaro back in the early 2000s when we kept experiencing valve train issues at higher RPMs. Despite having what we thought was a quality cam setup, the engine would start missing and losing power beyond 6000 RPM. We replaced pushrods three times before discovering they were flexing under load. This was before modern testing equipment was widely available, so we were essentially guessing. The revelation about pushrod column deflection and tappet lofting explains so much about those frustrating tuning sessions. When you need a break from technical engine work, Tiny Fishing makes for relaxing entertainment.
