The Stromberg 3-278 2-barrel carburetor is a legendary component in the automotive history of Mopar V-8 engines used in Dodge vehicles between 1961 and 1969.

The carburetor's body is made of durable cast aluminum, ensuring longevity and resistance to corrosion. The two barrels are mounted on top of the main body, connected by a central intake manifold.
Each barrel comes equipped with a float bowl, which holds the fuel necessary for the engine's combustion process. The float bowls are designed to maintain a consistent fuel level, ensuring a consistent fuel-air mixture is delivered to the engine. The carburetor utilizes a venturi design, which creates a vacuum that draws air into the carburetor and mixes it with the fuel for optimal combustion.
The Stromberg 3-278 carburetor features a power balance system, which allows for the even distribution of fuel and air to all cylinders, improving overall engine performance and power output. This system is achieved through a unique design of the carburetor's secondary circuit, which provides additional fuel to the engine under heavy load or high RPM conditions.
The carburetor is also equipped with a choke mechanism, which allows the engine to be started more easily in cold conditions. The choke mechanism is controlled by a lever on the carburetor body, which can be easily engaged or disengaged as needed.
The Stromberg 3-278 carburetor comes with adjustable jets and needles, allowing for fine-tuning of the fuel-air mixture for optimal engine performance. The carburetor also features adjustable primary and secondary idle circuits, which can be adjusted to maintain consistent engine idle speed under various conditions.
