The Ford C8AF-B carburetor, a legendary component of the 1968 and 1969 Ford Mustang 390 and 428 engines, is a masterpiece of automotive engineering. This quadra-bodied carburetor, designed specifically for the high-performance Ford engines during that era, is renowned for its ability to deliver powerful and efficient fuel delivery for a thrilling driving experience.
The C8AF-B carburetor features four venturi barrels, each with its dedicated fuel jet and idling jet to ensure a precise fuel-air mixture in every cylinder under various operating conditions. The primary and secondary metering rods, strategically located within the barrels, are responsible for controlling the fuel flow and maintaining the correct air-fuel ratio for various engine speeds and load conditions.
Incorporated into the carburetor design was a unique Four-Barrel Intake Manifold with Cross-Over Quadra Jet design. This innovation provided improved idle quality and idle mixture stability by facilitating the proper distribution of fuel between the three pairs of carburetor barrels at idle speeds. Additionally, it enhanced the overall drivability and power delivery of the engine by ensuring a near- constant, optimal fuel-air mixture during normal operation.
Another essential component of the C8AF-B carburetor system is the F4-4300 power packing. The power pack assembly plays a crucial role in maintaining a consistent vacuum to the carburetor and enhancing throttle response. It features a tuned-length, non-reclaimable, paper element air cleaner surrounded by a mesh filter to ensure the proper filtration of incoming air. The packing also includes a vacuum secondary, which maximizes the vacuum available to the carburetor, improving idle quality and enhancing engine power.
Lastly, the C8AF-B carburetor boasts a reliable fuel pump and float bowl design. The intake ports combine with the highly efficient design of the power packing to create a strong, consistent fuel feed to the engine. The float bowls, accurately sized for optimal fuel quantity and distribution, ensure proper fuel delivery while maintaining consistent level under various operating conditions. Overall, this robust and finely tuned carburetor system delivers consistent and reliable power for an unforgettable driving experience.
If you're looking to upgrade your classic 1968-1969 Ford engine with an authentic and high-performance carburetor system, the Ford C8AF-B carburetor is an excellent choice for those seeking the perfect blend of power and efficiency during that era.
