Aluminum Engine Intake Manifold

Aluminum Engine Intake Manifold, Satin finish, designed for BBC Big Block Chevrolet V8 engines (396–454). Constructed from high-quality aluminum, this manifold features oval ports, four corner water ports, dual distributor hold-downs, and nitrous bosses. The air-gap design allows airflow under the plenum to reduce heat transfer from the engine, resulting in increased horsepower. Optimized for engines producing 600–700 HP with displacements from 396 to 454, it delivers outstanding torque and performance when paired with the right engine combination. Ideal for high-performance Big Block Chevy builds.
