6-71 BDS polished billet alum. GM type street blower. For the hot rodders that love the classic look of a 6-71 GM blower BDS has designed this blower similar in a appearance to its ancestor but with none of the porosity issues that a cast blower has when you put the shine on it.
Rotors are billet alum. three-lobe sixty degree that use double lipped seals to provide superior seal on the rotor shafts with hi-speed double row ball bearings and steel gears to keep the rotors in time. Billet alum. rear bearing plate, front bearing plate and billet front gear cover offer maximum strength and gives a superior polish.
EFI injectors with a 13.250" on center bolt pattern can bolt to the top of the blower as well as 4150/4500 carburetor adapters.
Top opening on the blower case is 12.50" x 4.00" as is the bottom opening. Front cover has a pressure relief and a oil sight glass installed.
