Big Carb For Big Engines

Mighty Demon 850 annular carb

New Mighty Demon 850 annular carburetor for big-blocks and big small-blocks.

A carburetor for docile street engines, this is not.


Demon Carburetion has introduced a new 850cfm carburetor with annular boosters for high performing big-block engines and large displacement or high-revving small blocks. 

Prepared with 1.560in venturii and intended to operate with 425 to 540ci engines with camshaft duration of 240-plus @ 0.050in valve opening, this new carb features mechanically operated secondary throttles and  removable air bleeds and idle-feed restrictors. 

The removable idle-feed restrictors are particularly helpful for perfecting the idle mixture on individual engine combinations—excelling with differing camshafts, cylinder heads, and intakes. For example, if the throttle plates are adjusted to the correct position yet the idle mixture is too lean or too rich and cannot be remedied by ignition timing, simply replace the idle-feed restrictors. 

This Mighty Demon features billet metering blocks and base plates as well as throttle plates mounted on Teflon-coated throttle shafts that prevent galling in the bores of the aluminum base plates. It also includes Demon's innovative single screw Idle-eze  adjustment, as well as four-corner idle adjustment, power valve backfire protection and a Ford kick-down linkage.
