We are now in the geezer zone.
How many these days have a clue what you just wrote, and what they are?
Had a Friend with the low salt version 396 Chevelle, and man, did it pump up fast. What a buzzkill.
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.”
