4bbl Slant Intake

That's interesting. Can you tell us more detail about the test results you got with it? ;-)

(…because if we're just arguing based on what we see and what we think it implies, I can make at least as good a case that this design is superior to the Offy/Clifford/Weiand/etc types…)

Why don't you tell us how good it worked or if it has ever been on an engine?
I am sure anyone who has done all this 3d modeling has since run it on a dyno and has data.
