Carburetor Wedge Plate

The Carburetor Wedge Plate by Holley (MPN 717-2) is a precision metering component designed for tuners and engine builders who demand exact fuel delivery control in performance carburetors. This wedge plate serves as a critical interface between the main fuel bowl and the venturi circuit, allowing adjustments to fuel curve characteristics across the RPM spectrum. It's ideal for those looking to enhance the performance of their street machines, bracket racers, or classic restoration builds.

Holley's wedge plate design alters the relationship between bowl pressure and main jet restriction, effectively changing how fuel responds to accelerator input and steady-state cruising conditions. The plate's precise geometry creates variable metering angles that help mitigate fuel surge, vapor lock risk, and idle transition stumbles common in high-performance applications. Crafted with quality casting and machining, it resists fuel degradation and thermal cycling.

Carburetor specialists and engine builders rely on wedge plates when stock metering rods fail to achieve smooth throttle response or consistent cruise fuel efficiency. This component is particularly beneficial when swapping jetting combinations or adapting to changes in altitude, ambient temperature, or fuel octane. It integrates seamlessly into specific Holley carburetor models, ensuring optimal performance for serious carb modifications.
