Am I correct in assuming that relatively lower cylinder pressure is not necessarily a bad thing on supercharged engines? My cranking cylinder pressure is about 150-153 lbs on my 383/ B&M 144 combination. Normally, I'd like to see higher on a N/A motor, but I'm wondering if this could work to my advantage to help control the dreaded detonation under boost.
Also, I've read several (some conflicting) feelings on the benefit (or lack thereof) of going from 1:5 to 1:6 ratio rockers. My question has to do again with cylinder pressures. I'm running a dual grind Lunati (488/509 234/244) cam with 112 degree lobe separation, and 1:6's. Since the 1:6 change the cam duration slightly, could that be negatively affecting my cylinder pressures?
