Dynamic Compression and Aluminum Heads?

I’m on the other side of the static/dynamic debate. My personal opinion and from what I have learned from those who build engines, static doesn’t really mean much other than to calculate dynamic and dynamic means everything when trying to tune for pump fuel. When I had my cam ordered, it was custom ordered based on the dynamic compression ratio needed for the combo. After we ran the engine, it was dead nuts what they said it would do. Run on 91 octane with 11:1 old *** iron heads. Now if I were to put a different cam in and if it didn’t bring the DCR down enough, I don’t think there’s any way I’d be able to run pump gas safely, even with the same static CR as before. There are variables that aren’t accounted for in DCR, but i think it gives you a lot better and more information than static will ever tell you. That being said, I would NEVER build an engine to run on pump fuel based on the Static compression. I’d aim for the dynamic number. Just for the simple fact that my builder aimed for the dynamic number and it was perfect for my application. Just my 2 cents.
