The Sb Chry Action Plus intake manifold by Weiand is a performance-engineered solution designed for Chrysler engine builders and street enthusiasts who demand increased airflow and throttle response. This manifold addresses the factory intake's inherent flow restrictions by optimizing runner geometry and plenum design, making it an essential upgrade for naturally aspirated small-block Chrysler platforms seeking measurable horsepower and torque gains without forced induction complexity.
Weiand's Action Plus series leverages decades of manifold development to deliver superior port matching and runner velocity control, critical factors in cylinder head scavenging efficiency. The casting process produces consistent wall thickness that minimizes turbulence while maximizing effective flow area—a balance that factory iron manifolds sacrifice for cost and production speed. Weighing 21.45 pounds with compact dimensions of 14.8 x 7 x 22.3 inches, this manifold integrates cleanly into tight engine bays while maintaining the structural rigidity required for reliable high-RPM operation and thermal cycling durability.
Mechanics and builders working with Chrysler 318, 340, and 360 small-block engines will find the Sb Chry Action Plus compatible with both carbureted and early EFI configurations, though carburetor base plate modifications may be necessary depending on your specific intake adapter. Installation requires standard manifold gaskets and bolts; verify water passage compatibility with your engine setup for optimal performance.
