This kit converts an existing Holley Double Pumper carburetor to an aluminum HP main body for more horsepower, torque, and airflow, without the cost of a full carburetor swap. Removing the choke tower, choke control, and air horn reduces turbulence and smooths air entry into the venturi, and the kit is factory pre-calibrated for a wide range of applications.
