I'm curious how it compares to my CNC-ported Victors that show pretty simmilar flow #s but "should" (based on not being taken out to Max Wedge-sized entries) have a bit better velocity. FWIW, the MCSA I measured on the Victors yesterday is 3.05", although it gets quite a bit bigger as the runner opens up into the bowl over the short turn.

I belive on the 295 head is 2.8" Brian Hafliger
