Are you looking to transform your street carburetor into a high-performance racing carb without the hassle of a complete swap? If you can handle a screwdriver, you're on your way to boosting horsepower with the new Holley Aluminum HP carburetor main bodies. These retrofit kits allow you to upgrade your existing 650, 750, or 850 CFM double pumper to an aluminum HP main body, resulting in improved horsepower, torque, and airflow.

Thanks to the absence of an air horn, choke tower, or choke control, airflow is unrestricted, providing you with that extra power in a simple and cost-effective way. Each aluminum main body boasts a sleek, shiny finish and comes with everything you need to elevate your carburetor's performance!
