Decker Machine Twin Barrel

Those weird-looking venturi on the Decker Machine Twin Barrel carburetors available from Summit Racing are all about airflow. Instead of four separate venturi like a regular 4150-style four-barrel carburetor, the Twin Barrel has two large oval venturi that flow a lot more air than a similarly-sized four-barrel. For racers that want or need to run a 4150-style carburetor and can use Dominator levels of airflow, the Twin Barrel is ideal. Decker Machine Twin Barrel Carburetors are for gasoline or alcohol in 1,000, 1,200, 1,400 and 1,600 CFM ratings. Your choice of clear iridited or black anodized finishes.
