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!
