BBM 426 Hemi Dual Quad Intake Manifold for EFI

The Edelbrock BBM 426 Hemi Dual Quad Intake Manifold for EFI is purpose-built for serious performance enthusiasts running big-block Mopar 426 Hemi engines that demand maximum airflow and tuning precision. Designed for dual competition carburetor configurations adapted to electronic fuel injection, this single-plane aluminum manifold represents decades of Edelbrock's racing heritage and real-world validation on the dyno and street. If you're rebuilding a classic Mopar muscle car or competition vehicle with a 426 Hemi platform, this intake delivers the flow characteristics and structural integrity required for sustained high-RPM operation.

Constructed from premium aluminum and finished in natural (unpainted) form, the BBM 426 Hemi manifold features a single-plane design that promotes aggressive scavenging and optimizes intake charge velocity across the entire RPM band. The dual quad EFI flange configuration allows integration of modern fuel injection systems while maintaining the aggressive breathing characteristics of traditional dual-carburetor geometry—eliminating the compromises typical of retrofitted single-plane manifolds. At 20.34 pounds, the manifold balances structural rigidity with weight efficiency, critical factors when tuning ignition timing and boost response on high-output engines.

This manifold is ideal for restorers, race teams, and performance builders working with original Mopar 426 Hemi architecture who require seamless EFI integration without sacrificing the flow and character of a competition-grade intake. Installation requires proper fuel rail setup, gasket sealing, and ECU tuning to exploit the manifold's full potential; experienced Mopar shops and engine builders familiar with big-block Hemi platforms should handle fitment to ensure optimal results. The natural aluminum finish allows for custom coating or powder coating to match your engine bay aesthetic.
