Last chance to stop me from buying the hype...

again, not apples to apples comparison. I've got years of Holley experience and history. You have no experience with Demons (nor do I). You need to sharpen your pencil a little with these comparisons, you've not been close.

Well I've had five years straight with two Edelbrocks and most of the demon carb that were talking about runs on that theory with some thermoquad added to it.. of course on my 72 Duster I put a 600 Holley vacuum secondary and it worked fine. I had to fine-tune the tip in a little bit and get the lighter spring for the secondary but it did well...
