Intake Elbow 4150 Ford TB Flange

The Intake Elbow 4150 Ford TB Flange by Holley is a precision-engineered intake manifold adapter designed for carbureted engine builds and carburetor swaps on Ford-based platforms. This component is essential for hot rodders, restomod builders, and performance enthusiasts transitioning from stock fuel delivery systems to high-flow carb setups. It bridges the gap between modern carburetor designs and classic engine architectures.

Manufactured from either cast iron or aluminum, this intake elbow minimizes air turbulence and fuel distribution inconsistencies at the manifold-to-carburetor junction. The elbow geometry is designed to reduce flow restriction while maintaining even fuel atomization, which is critical for achieving consistent idle quality and throttle response. The 4150 flange mounting surface is precisely machined to ensure a leak-free seal against the carburetor base plate.

This adapter is ideal for Ford engine swaps, street rod builds, and vintage race car restorations where carburetor-based induction is preferred over fuel injection. Installation is straightforward and requires basic hand tools, making it accessible for anyone with fundamental mechanical skills. Its compatibility with various carburetors, including Holley and Edelbrock, ensures it meets the needs of a wide range of automotive enthusiasts.
