    Big Block Chevy

    The Speedmaster LowRise Manifolds are our lowest profile manifold and is also the only one that is street legal on pollution controlled vehicles. It is set up to accept a spread bore carb but comes with an adapter plate that permits the use of square bore carbs. To remain street legal with a square bore carb, you must use one that is also approved as street legal for your application.

    This Speedmaster LowRise manifold is a direct replacement manifold for the stock manifold on Chevy big block engines with general duty oval port heads. See note below for specifics. This manifold will not fit under the hood of Corvettes without hood modifications. Will not fit -tall block- V8s. May be used with OEM or aftermarket carburetors. For street applications use the stock Quadra-Jet carburetor. For street performance use a 650-750 cfm performance or double pumper carb and for competition use a 700-850 cfm double pumper. Note that the Speedmaster Manifold kit includes a carb adapter plate

    Low-Profile, Street-Legal Manifold

    Speedmaster's LowRise Intake Manifold is a direct replacement for a non-EGR engine stock manifold and is perfect for performance street machines and street rods. The LowRise Intake Manifold is designed with the lowest profile and is the only street-legal manifold that Speedmaster offers for use on pollution-controlled vehicles. This manifold will accept a spread bore carburetor and also includes a square bore carburetor adapter plate. Each aluminum LowRise manifold is cast from a steel mold to reduce porosity issues and is pressure tested for leaks.

    Note: In order to remain street legal with a square bore carburetor, you must use one that is approved as street legal for your application.
