Universal 680-CFM Hot Rod Series 4150 Carburetor (Vacuum Secondaries) by Quick Fuel Technology®

680-CFM carburetor with vacuum secondaries and adjustable fuel metering for street performance.

This 680-CFM Quick Fuel Technology® Hot Rod Series four-barrel carburetor is designed for street and performance applications using a compatible 4150-style square-bore intake. Its lightweight main body and accessible fuel-metering system allow engine-specific jet and idle adjustments. The vacuum-operated secondary throttles open in response to engine demand, making the carburetor suitable for changing street loads and gearing. Adjustable fuel bowl levels and replaceable tuning components simplify changes after installation. Verify the air-cleaner flange, choke provision, throttle linkage and intended engine range when selecting this CFM rating.
