The original 427 Medium Riser heads flow about 240@.500, 250@.600 and pretty much level out here. The original heads can be worked to flow some good numbers as well. We have done these heads several times and have gotten over 300CFM@.600 lift.
I will contact Blue Thunder about the new FE heads. They had told me they would be out around the first of the year. I will post as soon as we find out something. Thanks Keith
