as with all edelbrock heads there is some cartridge roll out of the box on these..

ill post the ported numbers once im done,, though its the same exh port that is in the older mopar head, and the same intake port thats in a stage v head once ported.

dwyane sent me an indy sr head to flow for him to see how the numbers compared from his bench to mine awhile ago,, once he bought a bigger bench,, the numbers were very close...

chris,, i dont think dwyane has a happy bench..
