A Great Choice for Hot Rods below 400 Horsepower
Styled and calibrated for Street Rods, slightly-modified Street Machines, and light trucks, Road Demons are impressive 4-barrels with a smooth choke tower design, vacuum secondary, and patented air entries. They are entry level, general performance carburetors with strong throttle response designed to replace most standard square flange carbs with a camshaft duration up to 220° at .050".
Note: Demon float bowls use special 9/16" x 24 TPI inlet fittings available in standard, filtered, or swiveled sizes.
