The Mighty Demon™ is perhaps the best value for the dollar in the four barrel carburetor market today.
It directly replaces Holley® HP models. It features billet–aluminum metering blocks, billet aluminum baseplates, large capacity fuel bowls complete with patented sight glasses and patented, streamlined air entries. Some of these features are found only on modified 4 barrel carburetors costing much more, and several are available only on Demon Carburetors. These innovative ideas allow the new Mighty Demons to produce more power and achieve higher levels of performance than conventional designs. All Mighty Demon™ carburetors come with a "General Competition" tuneup.
For high output street engines and for race engines, the Mighty Demon™ delivers the best performance value for the dollar!
