Holley Carburetor 850

Bought this carb off Pro Max Carbs out of Indianapolis at the Indy Mopar swap meet. I have decided to go with a different carb this is a 850 mechanical secondaries 50 cc accelerator pumps milled choke, blue non stick gaskets . It has been tested and tuned and ready to roll it has not been bolted on my car or used by me . Thanks guys
