BBC EFI R/P Intake Manifold w/4500 Flange

The BBC EFI R/P Intake Manifold with 4500 Flange from Holley is designed for serious Big Block Chevrolet builders who seek maximum flow and reliable electronic fuel injection integration. This single-plane manifold is tailored for high-RPM power delivery, making it ideal for both street and strip applications where traditional carbureted options may not suffice.

Constructed from quality aluminum alloy, this manifold weighs 22.9 lbs and measures 13 by 12.5 by 24.5 inches, ensuring it fits well in most engine bays while maintaining structural integrity during high-performance use. The integral EFI provisions eliminate the need for costly adapter plates, simplifying installation and minimizing the risk of vacuum leaks.

This intake manifold is particularly beneficial for BBC enthusiasts working with 427, 454, or 502 displacement engines, as it prioritizes tuning flexibility and repeatability over carbureted consistency. Its 4500 flange configuration allows compatibility with Holley's range of EFI throttle bodies, optimizing air velocity and distribution across all eight cylinders.
