Power+Plus is the newest line of performance intake manifolds available. As a result, they have been able to incorporate many new features in their manifolds not found in competitive models. Some of today's most popular manifolds were designed 30 years ago and the makers have never bothered to update the tooling to include many of the new features desired by performance enthusiasts. Professional Products has engineered those features into their manifolds.
The Cyclone manifold is the ideal street manifold. It is street legal on a wide range of applications (see catalog for details) and provides significant increases in power and torque.
- Manifold includes adapter to use a square bore carb
- Features dual distributor holddowns
- Includes two pipe tapped rear water ports
The 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. |
