I like Mopars and I like Hemis, but I cannot see how the Hemi can "get away"
with more compression than a wedge for the same octane.
I have always read that the Hemi combustion chamber is more detonation prone
and needs more octane. Or, more cam duration to bleed off pressure under 3000 RPM.
Unless you guys are comparing aluminum Hemi heads to iron wedge.
