680CFM Carburetor - Hot Rod Series

The 680CFM Carburetor – Hot Rod Series by Quick Fuel Technology is designed for street and strip applications, providing responsive throttle control and optimal fuel atomization for enhanced engine performance. This carburetor is ideal for builders and enthusiasts who seek reliable starting, smooth idle quality, and consistent power delivery across a wide RPM range without the complexity of electronic fuel injection.

Engineered with precision-machined aluminum castings, tuned fuel bowls, and calibrated metering circuits, the 680CFM carburetor ensures consistent jetting across varying loads and temperatures. Its vacuum-secondary design prevents fuel dumping during acceleration, maintaining clean carburetion and eliminating flat spots or hesitation. Internal fuel passages are optimized for droplet size and distribution, maximizing combustion efficiency.

This model is suitable for builders running carbureted platforms with engine displacements between 305 and 383 cubic inches, and it is compatible with standard two-barrel mounting flanges on most traditional muscle car and hot rod intake manifolds. Weighing 9.59 lbs, it offers a compact design that fits well in various engine bays.
