Question on port matching

Nothing you say addresses the FACT that it was only 10 HP down @ 5600 RPM ie maximum airflow demand. Is that because it contradicts yours and others dogmas concerning what it should have made? The fact that it was only down 10 Hp against what is recognized as the best dual plane on the market for smallblock mopars is nothing less than hilarious.
Maybe just another outlier event to be ignored........Or maybe just another one of those "combo' thingy's :lol:
