Very nice; hard to get this info. Where are the measurements taken? I.E., push rod pinch or down stream from there? Thnx

far as I know on a sbc it's always the pushrod pinch area the minimum. Unless you have a raised runner head. I think afr's 245, 23 head all the pushrod pinch area may be gone on it. AFR one of the few that lists there minimum CSA in there specs.

Also, the listed cc’s for an intake port, may or may not be actual measurement. Ex. Edelbrock performer RPMs were listed at 170ccs, while actually measuring 185cc. I believe they now list them at that...
