Anybody else do the E21 Intake Runner conversion?

[lloyd]

The math is not ambiguous at all. Ram intake volume and intake runner volume are different measures. Why should runner volume also include head port volume? Answer: it shouldn't, it is a different measure.

My examples of ambiguity were poorly chosen and incomplete. I was referring to MM's numbers and the conclusions drawn therefrom. MM deserves credit for offering a fair amount of information. Two oft quoted provisos seem appropriate: "Your mileage may vary." and sometimes "You get what you pay for!" :wink:
