Overview

The Demonology Road Demon carburetor is a 650 CFM, polished aluminum carburetor featuring vacuum secondaries and a down-leg design. It is constructed with an all-aluminum polished body and billet metering blocks and base plate, making it 40% lighter than original Demons. The fuel bowls have been redesigned for a sleeker appearance and include dual threaded inlets, dual sight glass windows, and internal baffling for improved fuel slosh control.
Show original supplier description
The Demonology 650 CFM Road Demon carburetor represents a next-generation upgrade for street and strip applications. Constructed from all-aluminum with billet metering blocks and base plate, it is notably 40% lighter than its predecessors. This carburetor is completely re-engineered and re-calibrated to offer improved drivability and full-throttle performance. It includes a re-designed throttle lever with integrated kick-down options for Ford A/T, 700-R4, and Chrysler transmissions. This specific model is designed for Ford Thunderbird vehicles from 1955-1979. However, please note that Eckler's no longer carries this particular carburetor and advises checking for updated selections.
