Thank you for the reply TNT. Its been many years since I had a Dart, around 40, and I forgot how to figure all that stuff out. Its a little higher than I wanted but what the heck
I kind of reverse engineered your question because you lack some of the volume measurements to figure it out otherwise.
I know that cam has a ICA of 60 degrees if installed per manufacturer specs, what your bore and stroke is and the length connecting rod a 340 uses. By entering this information into Wallace Racings Dynamic Compression Ratio Calculator I was able to find a static compression ratio that would end up having the compression psi you listed. It also lists the DCR value once your cylinder psi was matched. I left the elevation blank which is sea level.
