The heck with the filters, I'm getting a 390 Holley for my slant six

Thanks for the info

Back to the confusing chart, I think it was made with a carb or other restriction (only logical explanation with the data we have), and that in some cases makes some sense, because for instance, whats the point of doubling(?) a filter's area, if the gain is very small because of the limits of the carb? Besides everyone pretty much agrees we already know doubling a filters area (same), will double airflow.

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
