Speedmaster 1-147-002 Compatible with Chevy SBC 350 1957-95 (Non EGR) LowRise Aluminum Intake Manifold [Polished]

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 for the stock manifold on 1957-95 Small Block Chevy non-EGR engines. Includes special adapter bushings to fit 1987-95 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 our most popular manifold and is showing up on many performance street machines and street rods. 50 STATE LEGAL.
