The R6486A features a 670 CFM (cubic feet per minute) venturi size, making it ideal for smaller engines or applications where a larger carburetor may be overkill. The barrel body is made of aluminum, which not only looks great but also helps keep the weight down. The carburetor comes with a 650-1000 CFM double pumper intake manifold, allowing for a wide range of engine sizes and power levels.

One of the standout features of the R6486A is its fully adjustable primary and secondary circuits.

The secondary circuit, which controls the fuel mixture during acceleration, can be adjusted via screws located on the side of the carburetor. This level of adjustability allows for precise tuning, ensuring optimal engine performance.

Another feature of the R6486A is its electric choke system. This system makes starting the engine in cold weather a breeze, as it automatically engages the choke when the ignition switch is turned on. The choke can also be manually controlled via a switch on the side of the carburetor.

The Holley R6486A Barrel Carburetor is also designed to be easy to install. It comes with a numbered installation guide, which makes setup a straightforward process. The carburetor also features a removable float bowl gasket, making it easy to change the gasket if needed.

In terms of appearance, the R6486A has a classic look that is sure to appeal to both performance enthusiasts and those who value the aesthetics of their engine bay. The carburetor comes with a chrome top and a black base, giving it a sharp, contrasting look.
