Custom, dual quad intake manifold with 2 new Holley 6299-1 (390 cfm) carbs (total airflow 780 cfm). This manifold is based on a vintage Offenhauser dual quad manifold for the late-model (1965 – 1979) GTO cylinder head bolt pattern. It features a separated water crossover so the manifold can be removed without draining the cooling system. The exhaust heat crossover has been removed, and the manifold is provided with professionally fabricated blockoff plates for the head passages. All parts are either new or completely refinished to like-new condition. Would be cool for a street-machine GTO with aftermarket hood/hood scoop. Price compare to the Edelbrock dual quad systems being sold for Small Block Chevy with AFB carbs for $1300… Asking $1200 plus shipping.
