Aussie 250 2v cc per ten thou cut

Post #1 by 63falconATX » Wed Apr 25, 2018 1:41 pm

Forgive me if this has been covered, searched pretty well but didn't find a definitive answer.

Does anyone know the cc per .010"(.254mm) cut on a non crossflow 250 2v head? I know it could vary depending on how deep in the chamber but generally speaking from a 53cc starting point.

I'm actually looking for confirmation. I the modeled profile of the chamber opening in CAD and found a volume of ~1.42cc per .254mm cut.
