The Shelbys received the Stage 2 port job from Shelby Enterprises. Not sure about flow numbers.

Cal Metal posted a graph recently that shows the Shelbys do flow better than the Edelbrocks. And these are ported, so should show even more improvement over the unported Edelbrocks.

I suppose I should point out that the short block has no heads bolted on at this point. On my left, Edelbrock. On my right , Shelby. How about it, FE fans? What to do...
