I found my Cranking Cylinder Pressure (CCP) problem

When I put my combination together for the 408 I built using trickflow heads I used Wallace racings Dynamic compression calculator and with the 11.2 compression I was having it setup at and the solid lift cam specs showing closing at 65 ABDC it gave me a dynamic compression of right at 190.

Wallace Racing: Dynamic Compression Ratio Calculator

After the engine was built we tested then and they were all 190 to 200 so the calculator was real close and I have had no issues with detonation on 92 octane. That is initial at 16 total at 35

I guess I am just saying those calculators are pretty accurate. I was shooting for as much cylinder pressure as I could with 92 octane.
