IMHO much of the "dynamic compression" commentary is over-rated.
Every engine has its full stroke volume compressed at its torque peak, and frequently well before (obviously reduced proportionate to VE).
Exactly when that happens is a function of IVC point vs. RPM: a mild engine will capture more of its stroke length at low speed, and flatten out. A hot engine will have lower trapped volume at low speed, and (if the cam choice is correct) turn fast enough to capture its nominal volume at higher RPM.
If you still have dynamic compression in your power range, one of these things is true:
1. bad observation and/or bad analysis of data
2. wayyy too much cam for the RPM range
3. more static CR will generally help, but not always
Harley-Davidson's very efficient flathead race engine (KR) used 270° @ .050" cams for 7,000 RPM peak power... with 5.5:1 static compression.
