QuickFuel 880 Surging/Missing At Wide Open Throttle

Well....I tried 77's in the primary, left the 84's in the secondaries and found it really lean. Plugs where pretty white. So, went with one size smaller than stock with 79's in prim and 85's in secondary. Found this rich, strong fuel smell, and didn't get rid of my surging issue. I put the 78's and 84's back in for the recommended elevation, set the idle mix screws with the vacuum gauge and have now turned my attention away from the carb and timing as I have spent a lot of time testing and playing with those two areas and believe they are ok.
With that said, I think I should be looking at either a fuel supply issue or spark issue, as this surging/missing is only under load. Worse under load at lower speeds but a bit better but still there at WOT. I have checked by .008 gap in the 4 year old Summit bought Mopar Performance electronic ignition distributor, changed cap and rotor, new plugs and MSD wires, new MSD Blaster Coil. The only thing left I can think of is to try a new chrome Electronic Control Module (isn't even the dreaded Orange box) and ballast resistor.

My fuel sits at a constant 5psi when engine started but seems to drop to zero after when running for a bit. Must be a gauge issue or piece of crap getting into the gauge and blocking it off as it still runs ok at idle and when cruising down the street. I have two of the 3/8" hose with clamp style canister filters that you can buy anywhere, one before the Holley Red electric pump and one just about a foot before the 880 QF carb on 3/8 line throughout.

Not really sure where to go next......but guess I better get that fuel pressure to show a constant 5 psi, first and foremost. I'll swap out the old filters with two new ones and likely buy a new pressure gauge.

Anybody have any suggestions, thoughts, ideas or opinions?

Thanks.
