So how come no one is talking about the DCR?
I am trying to work through this question myself (another thread), but it would seem the Dynamic Compression Ratio is really what one needs to be looking at as that accounts for the valve timing events (which are courtesy of your cam).
As such, what I would love to know is the matching OCTANE<=>DCRs people have successfully ran with?
To re-hash that other thread:
previous 360 motor with 10.5:1 static and HE3844 flat tappet:
Static compression ratio of 10.5:1.
Effective stroke is 2.91 inches.
Your dynamic compression ratio is 8.72:1 .
Your dynamic cranking pressure is 182.97 PSI.
Your effective boost compression ratio, reflecting static c.r., cam timing, altitude, and boost of 0 PSI is 8.72 :1.
V/P (Volume to Pressure Index) is 162
