Yes. As you go down in cam size, cylinder pressure increases because the intake valve closes earlier and earlier in smaller cams so that builds more cylinder pressure.

You cannot run much over 9.2:1 on pump gas with iron heads and no quench. Certainly not 10:1 or close.

RustyRatRod is the compression ratio you are talking about static or dynamic? I'm learning as we discuss this. Thank you for your input.

I ran some number through the calculator on Keith blacks website. I'll attach a picture of those numbers. Of course these are hypothetical numbers based on a best guess of how the motor is set up. I really need to pull the heads and "blueprint" the top end of the engine.
I think I've input the numbers correctly.
