LOL!

I have no problem with being in the Geezer Zone! I am a Geezer!

To clarify, anti-pump up lifters were hydraulic lifters that had bleed holes in them and allowed a higher RPM before encountering valve float.

I shifted my first ‘65 GTO at 6500 RPM. Stock GTO engines of that era encountered valve float at roughly 5500 RPM.

My current engine is good for 7000 RPM, but I have a 5500 RPM “pill” in the MSD 6AL. It is a “street” engine with too much cam and compression, but since I do not race it, there is no need to spin it to 7000, so I don’t.

It is, with the 3” Pypes exhaust, a badass, fun “Sunday Driver.”

Oh yeah, I knew what they were, just funny how I also knew how few FReepers would have a clue what you were talking about. Never had to deal with them.

I still remember learning to set the valve clearance on the solid lifters of my '67 427/435 HP Corvette. Some clown told me to do it while running. What a smoky, useless mess that was.

Many decades later, I know much better. Too bad the Corvette is long gone. Motorcycle engines are excellent training tools.
