You are bidding on a used factory four barrel intake manifold for all 1977-84 Buick 3.8 and 4.1 liter V6 engines. It can use a good cleaning, but it's got smooth gasket surfaces and good threads in the bolt holes. Thr thermostat housing and throttle cable bracket are included. I've also got a Holley Economaster 450 cfm carburetor listed that would work well with this intake that ends on April 18th. Happy bidding!
