The item for sale here is Vintage Original 6-71 GMC Detroit Diesel Blower.  This neat supercharger came out of an estate in the Bay Area of an old racer.  He loved vintage speed parts and this was part of his collection.

The supercharger seems to be in good used condition.  Still has the factory blue paint on it!  Don't know a lot about these but looks to be a nice original.  The end has a slight dent on the right.  Not sure if it moves, tried to get the rotors to turn and they don't seem to turn.

Shipping is a flat rate of $100.00 in the US, $250.00 to Canada and $400.00 elsewhere.  Buy more items from us and we will gladly combine shipping! Shipping would be more to Alaska or Hawaii.
