Description
Holley 850 CFM Annular Vacuum Secondary Carburetor comes with an electric choke and is custom built. We set this carb up with threaded air bleeds, idle feed restriction and power valve restriction. The carburetor also features an adjustable vacuum secondary cover which allows you to change the opening rate of the secondaries without removing anything from the carburetor. This carb is ideal for a street driven 500-600 hp motor.
