SB Chevy Cyclone (EGR) Polished Finish. The Power+Plus PS (Performance Street) manifold is the ideal street manifold. It is street legal on a wide range of applicationsand provides significant increases in power and torque.

The Power+Plus Cyclone Manifold is a direct replacement for the stock manifold on 1957 - 95 Small Block Chevy 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. Power+Plus 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 Power+Plus 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.
