Anyone have any idea what the approximate cc's are of a chamber on a 346 head off a 440?

The advertised cc's are 81 but the actual number will be closer to 90. I've personally measured from 88 to 91 cc's on 346 heads.
Pardon me but my karma just ran over your dogma.

 :iagree: Most open chamber heads come in at 90cc or very close to it.
