Race-bred performance for the street

The Street HP Series of carburetors from Holley use the best features from their race bred 4150 HP carburetors, but they are tamed for the street and light competition use. The Street HP Series of carburetors feature a contoured main body with screw in air bleeds for precision tuning capabilities. Available in either mechanical or vacuum secondaries, there is something for everyone. The mechanical secondary versions even feature four corner idle capabilities for precision idle control. These Street HP carburetors are available in a shiny finish or a classic gold dichromate finish that gives you the classic Holley carburetor look.
