What a pain..Obviously I need lessons on how to post..This thing is a 300hp327 factory cast iron manifold datedSept 66 with a Carter AFB 3721SB 4 BBL carb for a standard tranny I believe. Sand blasted and painted. Minus a coil brkt. Thermostat hsing is B-Body.Corvette thermostat hsing is different. The carb has been kitted and is very clean...needs a throttle linkage bushing. Needs a filter element. The exact manifold is on my 63 at the moment dated Jan 65..I can swap it out if required for authenticity...Heavy to ship but if ya need it I can come to the party here!
