Hey Brian, I meant no dis-respect bud, I believe You've helped me on some issues with my Demon before, I'm sure you kow your stuff, & I know You are right that normally the way to hook it up is to ported vacuum, I just wanted to ad in that in some case's like mine, I had to hook it up to direct vacuum & i thought it was interesting that in the edelbrock owners manual they say it's okay to hook it to manifold vaccum when you have a long duration/radical type of Cam that might require more vacuum at idle.

This is a good discussion topic, believe me I was kinda freaking out that I had to hook it up wrong until I found that section in the owners manual.
