Street Demon carburetors are known for their clean looks, ease of use and revolutionary design. This design ensures a
stable idle, crisp throttle response, and smooth performance. Their optimized calibrations and dual mounting pattern make
them Run-Ready™ for a large variety of engines and vehicles.

All of the popular and innovative features associated with these carburetors are included in the Shadow Black version, plus
they utilize the Street Demon aerospace composite fuel bowl that keeps fuel up to 20° cooler. They have an integrated
fuel bowl/main body with all gaskets above the fuel level and no plugged passages to eliminate all potential leak paths,
Goggle Valve Secondary (GVS™) throttle plate, and much more. With Demon’s Shadow Black ceramic coated finish, you
can be sure that your car stands alone at the next race, show, or cruise-in!
