Dual quad question?

[Crazy440]

I have dual 600 cfm edelbrocks on my rig.  I've heard that when using progressive linkage, the back carb should open first.  Am I correct?  Would there be a problem if I opened the front carb first?
My set-up came with Edelbrock's dual quad progressive linkage.  I can't for the life of me figure out how to set it up so the back carb opens first.
Pictures would be great.
Thanks for any help.

yes, rear carb opens first...if front carb opens, then the rear cylinders will not get fuel from the primaries on the front carb

I got dual quads on my Charger.....carbs are hooked together as one....no progressive linkage

That's how I had them set-up.  Just thought I'd try the progressive.

I have a  tunnel ram on mine and that is how I have mine hooked up
