Well friends BDS has made this billet alum. plate adapter that allows just that. Simply bolt the plate on the manifold with provided hardware, install the blower and this plate moves everything forward by an inch.
Plate is made from .625" thick billet alum., edge that is seen between blower and manifold is polished, surface between blower case and adapter plate is O-ringed for a superior seal but bottom side is not, opening is 12.00" x 4.125" on the top and bottom is 11.250" x 4.125" on the bottom. Plate dimensions overall is 15.875" x 12.250".
May require some belt and blower drive adjustment for final fit.
