I'm at 4 psi right now. Edelbrock specified 4-6 but general consensus online is edelbrock carbs are very picky about fuel pressure - idk if it’s an inherent design flaw or just a design choice of the needle and seat, but apparently pressure doesn’t really matter - as long as it’s enough to put fuel in the bowl faster than the engine uses it you’re good. I used -6 AN from tank to carb and the pressure fluctuates a little from kind of 3 psi to 5 or so. I figured I’m in good shape.
