BBM Torker II Manifold - 413-440

The Edelbrock BBM Torker II Manifold 413-440 is a single-plane aluminum intake manifold engineered for maximum airflow and performance on big-block Mopar RB-series engines. This square-bore design delivers enhanced volumetric efficiency across the RPM range, making it a proven choice for builders seeking reliable mid to high-RPM power delivery without sacrificing street manners. Available in natural aluminum finish, the Torker II has been the benchmark in Mopar intake technology for decades.

The single-plane configuration routes all cylinders through a unified plenum chamber, which concentrates air velocity and improves fuel atomization in the combustion process. This design excels when peak power demands occur at elevated engine speeds—typically 4,500 RPM and above. The manifold's casting quality and internal flow passages have been optimized to minimize turbulence, allowing larger-displacement RB engines (413 and 440 cubic inch variants) to breathe efficiently without unnecessary restriction. Weighing 15.25 lbs, the aluminum construction reduces overall engine bay weight compared to cast-iron alternatives, a consideration that matters for both handling balance and fuel economy in street applications.

This manifold is purpose-built for Mopar enthusiasts restoring or building 440 Magnum engines and 413 big-block platforms. Whether the application is a vintage muscle car seeking authentic period-correct performance, a hot rod builder targeting reliable street cruiser power, or an engine shop constructing a customer rebuild, the Torker II's track record of compatibility and straightforward installation makes it the go-to intake for RB-series applications. The square-bore design ensures proper carburetor/throttle-body alignment across OEM and aftermarket fuel delivery systems commonly paired with these engines.

Edelbrock's Torker II has remained in continuous production and high demand because it delivers verifiable gains in flow and power without requiring custom machine work, exotic fuel systems, or exotic tuning. For builders committed to proven, repeatable results on Mopar RB-series platforms, this manifold represents the industry standard. Part number 5091, SKU EDE5091.
