Used intake manifold.  The is the lower mount of a Tuned Port Intake.  This is GM# 14081005.  This fits 85-86 Camaro/Trans Am 305.  This intake has the additional NPT port for the cold start injector switch (not included).  This does not fit 87 and newer heads with the angled center bolts.  This is not compatible with Corvette vehicles as it does not have the coolant crossover port in the back of the intake.   This intake is in good condition, there is some minor pitting around the thermostat seal area as well as one of the rear coolant block-off ports.  Fits the following:
