This auction is for used but in really good condition Cast Iron 2-Barrel Intake manifold for a Buick 300 V8 4.9 Liter. This manifold was removed from a 1966 Buick 300 engine. See pictures for casting numbers. Please note this manifold is quite heavy (approx. 38 pounds) and shipping costs will be a bit high. Nonetheless, for the price I am offering it, you will get a better deal than other (higher priced) manifolds for sale here on Ebay
