Test test test

You guys that think this way are totally wrong when talking about a head like a small block Mopar Speedmaster or Edelbrock head. I try to share what I learn but if you want to be a cement head, help yourself. All heads are not alike, and all chambers are different animals.
I think that's a little unfair, don't think anyone knocking your work just I think It's natural to assume the chamber shouldn't be bigger than the bore, even though that's probably only based on assumptions without any empirical evidence, I sure someone out there had dyno/track test the **** out this but most of us not privy to this info, so when someone does exceed assumptions it might bring up some questions.

From what I remember your testing on a 4.03" bore so if your gaining 20+ cfm by going larger than bore especially if you found it's the only way to gain this then the results speak for themselves, cause it's fair to assume that gain will also apply to the dyno and track. I imagine there would be some more gains on larger bores. Have you ever tested them on larger bores ?
