    You asked for it and Holley delivers!

    The famous Holley HP main body found in every pre-2012 NASCAR Cup winner is now available in a retrofit kit to update your Holley Double Pumper. Holley has taken the science of fuel technology and introduced a retrofit package that converts your tired 0-4777 (650cfm), 0-4778 (700cfm) or 0-4779 (750cfm) (shiny or dichromate) into a race ready, high flow 750 CFM HP style carburetor with simple hand tools.

    Detailed instruction sheets with photos and all parts necessary for the conversion are included for simple installations, even by novice enthusiasts. A few minutes are all it takes to eliminate that restrictive choke tower and linkage and give your engine the airflow and horsepower it has been looking for.

    Don't settle for a cheap overseas knock-off, demand what the racers demand. Demand Genuine Holley!

    Rated 5 out of 5 by from Improvement Bought this to correct some issues with a modified main body (milled choke horn) noticed big improvement in throttle response, 95% reduction in hesitation in my case. Came with squiters, air bleeds, and jets for a good base setup. Metering block to main body gaskets were torn from packaging, but for the overall price still pleased with the product. Possibly the most bang for the buck in upgrading your carb.

    Rated 5 out of 5 by from Best carb I've owned The 750 hp works period. I tried the newer blacked out version with dissapointment. Couldn't get the hesitation out. This earlier version works great!
