Mopar Big Block 413-440 V8 Dual Plane Aluminum Intake Manifold - Satin

Upgrade your Mopar RB-Series big block with the Top Street Performance Dual Plane Aluminum Intake Manifold. Designed for carbureted 413, 426 Wedge, and 440 cubic inch Chrysler RB big block engines, this satin aluminum intake manifold is engineered to improve airflow, throttle response, and torque across a broad operating range. The dual-plane design provides excellent street manners while supporting the airflow demands of performance street, street/strip, restoration, and restomod builds.

Constructed from lightweight aluminum, this intake manifold helps reduce weight compared to factory cast iron manifolds while promoting improved heat dissipation and engine efficiency. The satin finish delivers a clean, show-quality appearance that complements muscle cars, hot rods, and custom engine compartments.

Designed for operation from 1500-6500 RPM, the manifold's runner and plenum design support balanced airflow distribution and strong low-end torque while maintaining responsive mid-range power. This makes it an excellent choice for vehicles that spend most of their time on the street but still require dependable performance under aggressive driving conditions.

The low-profile design helps improve hood clearance in many applications while maintaining compatibility with standard deck RB-series engine configurations. The manifold utilizes a single 4-barrel 4150 square-bore carburetor mounting flange, making it compatible with many popular carbureted performance combinations.

Common applications include Mopar muscle cars, street machines, hot rods, bracket racers, and restoration projects powered by Chrysler RB-series big block engines. Whether replacing a restrictive factory intake or upgrading a performance build, this manifold delivers improved drivability and airflow for a wide range of carbureted applications.
