While Ted is working out the best carb combo/573 Edelbrock manifold setup,I was wondering if Ford was the only one that made a 2x4's manifold or did the after market make any?If so,which one was the best(like the 573 Edelbrock for tri-power)?I know that Ted's hands are full with all the dyno testing the tri-power setups"BUT"----How about a carb/manifold shootout between the best Tri-power vs dual quad vs John Mummert's new alum. 4 barrel manifold/4 barrel carb(Holley-Road Demon-Edelbrock ?) tested on a medium built Y-Block(only thing that changes is manifold /carb combos)!Might save some of us a few $  on the carb/manifold choice for our particlur engine combo(although tri-power sure looks kool).KID
