I called Holley to ask about these Quick Fuel plates, and the tech support actually told me they arnt as good as the Promax ones, they even went as far as to not recommend them because they arnt as "adjustable". I find this hard to believe considering once you have tapped ports for jets, that's where your adjustability comes into play. Anyone have real world exp with these different brands of plates? Between the Promax plates and fuels lines, jets/springs etc and time to tune this 6 pack, I hate to say it but I could buy a brand new 4 Barrel Carb and manifold and make my life simpler. I really don't want to go that route because honestly a 6 pack is awesome and I see very few people around me still running them.
