Sorry I got lost in all this(A.D.D.)
Anyone mention the the CFM HAS TO BE MEASURED AT THE SAME .....INCHES OF WATER?????
Edelbrock measure the 2brl and 4 brl at different vacuum
the two don't relate 500 cfm 2b is not a 500cfm 4b
Different manufactures do this a bunch
So you need some 'Day Standard' to really compair them
Oh AND I agree....parts kids don't know squat....
