Two ideas come to mind here. Mill a set of adapters to attach the Chevy intake to the Mopar heads. Probably more work than it's worth. run the new Indy Mod Man intake. Or like what has been stated here, run it on a single 4 barrel intake. Though my blower is bigger., It is a 6V-71 (not a 6-71) which in layman's term is 366 cu/in blower. Mild 340@3875lbs it runs 11.0@123.
