Anyone have exact flow numbers for the Holley Systemax and Edelbrock RPM intakes? Which flows the most out the box?

both are great intakes. ports on the systemax are close to a felpro 1262, those on the RPM are close to a felpro 1250. (i.e. systemax significantly better).
N/A it seems to be a push, and with fewer cubes perhaps a slight advantage to the rpm. forced or with more cubes, the advantage tips toward the systemax. when you get really serious (cubes + boost) consider the spyder or victor intake.
MM&FF I think a year ago did a comparo of all the intakes. On an N/A built 306, the systemax thrashed everyone, but the rpm was close. It was quite a revver though.
