Default Carbureted fuel pressure

Comparing optimum FP between a Qjet and an edlebrock 750 (model 1411) ... the Qjet is history and the 1411 is up & running.

I'm running 6.5 pounds of pressure with a fairly new (as of the engine install) AC Delco Vette style pump. Is that too much pressure for the Edlebrock series carbs?

that's what I'm hoping for! The Carb shop says 3.5 pounds of pressure, and suggests I put a regulator on it. Summitt Tech support says it's fine.

I have the summit regulator and gauge on my Edelbrock 600 cfm and have been using a little under 6 lbs.
