Aeroflow SB Chev Classic Dual Plane Intake Manifold, Natural Cast Finish AF6011-1000

Get the maximum power from your carburetted engine with this Classic Small Block Chevy carburetted cast intake manifold. This dual-plane intake manifold is designed to keep your air and fuel distribution going into the engine at a steady and even flow for maximum performance and efficiency. The carburettor-mounting pad is designed to accept aftermarket square-bore carburettors with either manual or electric choke options available on today’s market. Specifically designed for 262-400 cubic inch small-block Chevy engines operating in the idle to 5500 rpm range. In most cases, these manifolds accept late model water necks, air conditioning, alternator and H.E.I. ignition systems.

This intake manifold is equipped with EGR (Exhaust Gas Recirculation); therefore, they are compatible with exhaust emissions or emissions related components. A EGR block off plate and gasket are provided if you do not require the emissions components.Special adapter bushings are included to allow this manifold to fit the later model cylinder heads (1987 to 1995). You can choose to either use the angled bushings to bolt on accessories or use the straight ones if not using any accessories.

Included in this manifold kit is an adapter plate that converts the standard spread bore carburettor pattern over to a square bore carburettor. This will adapt any aftermarket carburettor with a square bore base.
