5.7 0r 6.1 with msd hemi 6 and carb

Anyone ever done any testing with the Indy Mod Man setup? I assume it would probably suffer the same fate of the XV and Mopar Performance carb style intakes with the shorter runners, but I was looking into running one since they seem to be one of the most affordable carb options. I still find it odd that you can get a dual quad Edelbrock setup for far less than a single quad XV setup...
