Edelbrock B/B Chev Rect Port RPM Air-Gap Manifold - Black Plasma Finish

If you're building a high-performance street Big Block Chevy with rectangular-port heads, this Edelbrock RPM Air-Gap intake manifold is a solid choice. It's designed specifically for 396 to 502 cubic inch V8 engines, aiming to give you more power by keeping the air/fuel mixture cooler. The unique Air-Gap design creates a space between the intake runners and the hot engine oil, which helps create a denser charge entering the cylinders. This manifold fits a wide range of classic Chevrolet vehicles, including models like the Impala, C10 Pickup, and Camaro from the mid-60s through the mid-70s.

What sets this manifold apart is its Air-Gap technology. By isolating the intake runners from the heat of the engine block, it helps maintain a cooler charge temperature. This cooler charge is denser, meaning more oxygen can be packed into each cylinder, leading to improved combustion and ultimately, more horsepower. The Black Plasma finish not only looks sharp but also offers good durability. This manifold also includes provisions for rear water outlets, dual distributor clamp locations, and nitrous bosses, making it adaptable for various street performance setups. It's designed to accept late-model alternator and A/C brackets, which is a practical consideration for street applications.

When installing this manifold, remember it's designed for high-performance rectangular-port heads. You'll want to ensure your engine build is set up to take advantage of the increased airflow potential. This part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for specific details regarding your build.
