.rebuilt by dale wilch, never installed by me NOT BILLET! Perfect proportions for sbc (6-71's and up look grotesque on small blocks, in my opinion.) perfect for street rod or late model pro street or if you just need an excuse to cut a big hole in your $100K NCRS restored Corvette. does not include front of rear covers. No blower drive parts. Will also be listing another 4-71, a core that includes front and rear covers. listing to follow PERFECT FOR YOUR McMULLIN DEUCE ROADSTER CLONE BUILD!
