PRO-250 2x4 Barrel Intake Manifold

The Collino PRO-250 intake manifold is engineered for Chevrolet inline-six engines, specifically the 292, 230, and 250 cubic inch displacements. Designed to accommodate both 2-barrel and 4-barrel carburetors, this manifold is an excellent choice for street performance, muscle car, Pro Touring, and other high-performance applications. Its internal design focuses on optimizing the air-fuel mixture's path and velocity, leading to more efficient and balanced distribution to the intake ports. This enhancement translates into improved throttle response, increased carburetor efficiency, and a notable gain in horsepower and torque across the entire RPM range. The manifold's top base is prepared to accept a variety of 2-barrel and 4-barrel carburetors from different manufacturers, offering flexibility for traditional or performance-oriented setups. This makes it an ideal solution for both direct replacement of original manifolds and as a significant performance upgrade for classic engines, all while maintaining reliability, durability, and a professional technical appearance. For specialized carburetor configurations, certain models can be mounted directly without spacer towers, which can be crucial in applications with limited under-hood space. Before installation, it is recommended to verify compatibility with your specific engine, carburetor, and available space. Proper installation requires the use of correct gaskets and adherence to specified tolerances for optimal sealing and performance.
