Hemi vs. Non Hemi chamber volume

Orig(most Popular #69730= about 22.8-23.4 cc. or Ml....... Same Thing; Yes they are because I know someone's going to say there different 60363 tend to run a little larger23-24.4, I do these heads for Preds. Daily and have 26 sitting here as we Breathe
These are T3 engines now right?

Nox is a major factor, not just HC emissions.
I wouldn't be suprised to see the combustion chamber volume increasing along with the the bigger bore and stroke.

People are throwing a lot of numbers around however....
My Hemi ended up being over 19cc after a lot of welding(fine for gas which is what I want), I agree with young it has a large chamber in oem form.
