71 and 72 Duster Twisters had Dual Scoops Identical to Demons....However they came with no larger than 318 2 BL. Also they had no hole in hood or rubber gasket that Demon had. Last :few years I have seem scoops on 340 dusters in division 4 with huge openings without Tech saying anything .......sowho knows what you might sneak thru with? Specs on 340 4.04 Bore/ 3.31 Str. John Irving DEF/Stock 71 Demon 275/314 HP.
