Great writeup on Dynamic Compression

Great article. The idea of a pump friendly high compression big cam engine is legitimized.
I'm kinda wondering about the 9.5 CR limit for iron heads I see everywhere.
I never see "9.5 CR unless you use a larger cam". Maybe I'm just missing it.
There is a member here who advocates higher compression, but I don't recall that being in association with cam bleed off.
The cylinder pressure test makes a lot of sense, with the goal of around 190, maybe 180 if planning to burn 87 octane. It's so much more real than a calculated CR.
Leak-down is likely way underutilized. I am familiar with it from my past in aircraft maintenance.
This will be good fodder for conversation with a cam grinder, prior to choosing pistons.
