Air Gap vs. Weiand, Performer/RPM, Holley, etc. (again!)
I did a search on this & didn't find anyone who had gone to an Air Gap from a regular dual plane or vice versa. Has anyone actually changed these out either way & noticed any difference?
It is interesting that "Super Chevy" got quite a broad performance gain in both HP & torque (w/a mild cam & heads) in their Danger Mouse motor when they went from a Weiand #8004 to the Air Gap. I'm wondering if thats true across the board?
