| The P52000 Power+Plus Cyclone 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. 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. |
