Pro-Series CNC Metering Block - Dominator

The Pro-Series CNC Metering Block - Dominator from ADVANCED ENGINE DESIGN is a precision fuel distribution component engineered for carbureted engines requiring accurate metering calibration. Built for serious engine builders, restoration specialists, and high-performance automotive enthusiasts, this metering block serves as the critical interface between your fuel bowl and primary/secondary circuits. Whether you're tuning a street machine, vintage muscle car, or competition engine, proper fuel metering is essential for consistent drivability, fuel economy, and peak performance across the RPM band.

This CNC-machined component delivers repeatable bore tolerances and precise flow passages that traditional casting cannot match, ensuring fuel distribution remains consistent cylinder to cylinder. The Dominator design optimizes idle circuits, transition ports, and main metering jets for responsive throttle response and smooth power delivery under load. Advanced Engine Design's metering block incorporates optimized orifice sizing and passage geometry that accommodates both stock and modified carburetor applications, allowing tuners to dial in fuel curves without extensive port matching or honing work.

This block is ideal for restorers rebuilding original Dominator carburetors and performance builders seeking OEM-equivalent or upgraded fuel delivery control. Its compact 4.1 x 2.05 x 6.2-inch footprint and lightweight 0.55-pound construction integrate seamlessly into stock and custom mounting configurations. Installation requires careful attention to fuel line routing, jet selection, and idle mixture tuning to maximize the precision this component provides—making it a worthwhile investment for anyone serious about carburetor tuning and engine optimization.
