Quick Fuel Black Diamond 4150 Carburetors

Quick Fuel Black Diamond Q-Series 4-barrel carburetors feature a Proform high-flow main body to help you achieve big-time performance on the dragstrip. The carbs include either down-leg or annular boosters, screw-in idle, high-speed air bleeds, accelerator pump discharge nozzles, and a blended venturi area. Their unique PTFE coating provides a durable satin black finish—it's impact- and scratch-resistant, and impervious to underhood chemicals. The coating also offers a six percent reduction in fuel temperature, allowing for improved performance. These carburetors have CNC-machined billet metering blocks with 4-stage emulsion to provide more precise fuel metering, improved throttle response, and a more uniform fuel performance curve.
