Gen 3 Hemi dual plane.
Fwiw I ran a 16x3 with a drop base on a modman with no hood clearance issues - but cant say oif our engine bays are any dedper than your Dusters and Barracudas.
And another comment - because this intake performs so much better than the Modman or other single planes - $$ spent on a light skimming of the carb pads would not be throwing good money after bad.
