Original NOS GM 1966 all Pontiac models with factory tripower cast iron intake. Manifold has very slight rust on flat surfaces and been painted the wrong year color but has CLEARLY never been bolted to an engine. All holes are clean and have never had a bolt screwed into them. Exhaust crossover has ZERO exhaust deposits. Manifold is much nicer than one that has been used and simply sandblasted. Date code is “D236” best I can make out.
