It's in a Word table that won't post.
M: 3 sizes 160-250 CFM @ 3.0 Hg.". This assumes that the total carburetion is small enough that the engine will pull 3.0" of WOT vacuum. If not, the actual CFM will be less. With large sizes multiply by .7071 to get the CFM @ 1.5 Hg.". For intermediate WOT vacuum, use the square root of the ratio of actual vacuum to 3.0 times the 3.0 rated CFM.
Depending on the carb and manifold the difference may be very small at WOT but give bad distribution @ part throttle.
