Review HOLLEY Ford Barrel Carburetor fits MUSTANG FALCON 1940–1969

The Holley R4454 carburetor is a high-performance, four-barrel carburetor specifically designed for use on 1964 to 1969 Ford Mustang and Falcon applications using a 1940 Ford flathead V8 engine. This carburetor is a direct replacement for the original Carter AFB or Holley 2300 series carburetors, offering improved performance and ease of tuning.

The R4454 features Holley's classic four-barrel intake manifold design with four separate throttle bodies that allow for precise control of fuel and air mixture for each cylinder. Each throttle body is equipped with a manual choke, allowing for easy starting in cold weather conditions. The carburetor also comes with Holley's unique Synergy base plate, which simplifies the fuel system plumbing and allows for easy installation of an electric choke and fuel pressure regulator.

The R4454 carburetor is designed with Holley's proven internals, including a 670 CFM gross flow rate, 410 CFM net flow rate, and a 0.060-inch bore size. The carburetor also comes with a 650 CFM dual-plane intake manifold, which provides excellent air distribution and helps to reduce intake manifold vacuum leak issues. The carburetor's meticulously machined components ensure a proper fit and excellent sealing, eliminating the need for shims or excessive adjustments.

The R4454 carburetor's design allows for easy tuning and customization. It comes with Holley's unique vacuum secondary system, which allows for precise tuning of the secondary circuits for optimal engine performance. The carburetor also comes with adjustable primary and secondary idle circuits, allowing for easy adjustment of the engine idle speed.

The R4454 carburetor is constructed of high-quality materials, including a billet aluminum base and brass bodies, ensuring durability and longevity. The carburetor also comes with a set of Holley's legendary vacuum secondaries, which are known for their excellent response and power delivery. The carburetor's brass fuel bowls are coated with Holley's exclusive Duramax coating, which provides excellent corrosion resistance and helps to prevent fuel from evaporating.

In summary, the Holley R4454 carburetor is a high-performance, four-barrel carburetor specifically designed for use on 1964 to 1969 Ford Mustang and Falcon applications using a 1940 Ford flathead V8 engine. It offers improved performance, ease of tuning, and durability, making it an excellent choice for enthusiasts seeking to enhance the power and drivability of their classic Ford vehicles.

Details:

I don't know if it needs rebuilding or will work as is. I don't need the other one. I had bought 2 of these and put one on my Falcon.
