    Speedmaster Auto Parts

    Buick Century 5.7L 1977-1979, Holeshot Series Carbureted Intake Manifold by Speedmaster®. 1 Piece. This top-grade product is expertly made in compliance with stringent industry standards to offer a fusion of a well-balanced design and high level of craftsmanship. Manufactured from industry-leading materials using up-to-date equipment, it ensures everlasting reliability and enduring value. This product is distinguished by total quality assurance, unsurpassed by anybody else. Speedmaster Holeshot Manifold is a direct replacement for the stock manifold on 1957-95 Small Block Chevy non-EGR engines. Includes special adapter bushings to fit 87-95 engines. Use the stock Quadra-Jet carb or 500-650 cfm vacuum secondary carburetor. Kit includes adapter plate to permit use of certain square bore style carburetors. Manifolds are cast from steel molds, not from sand molds. Permanent molds provide a tighter grain casting thereby reducing the occurrence of porosity which can mar the polished finish. Additionally, each Manifold is 100% pressure tested for leaks to eliminate installation problems. This is Speedmaster most popular manifold and is showing up on many performance street machines and street rods.
