Holley’s new 0-4779SA is constructed from aluminum. Compared to its zinc counterpart. Holley’s aluminum 0-4779SA will hold its shine longer and also can be hand polished for a custom look!
This Holley Double Pumper® carburetor is a perfect performance upgrade for hot street cars and race vehicles. The Double Pumper carburetor is an American icon when it comes to performance. From its roots as the premier carburetor on many factory muscle cars to powering thousands of vehicles across the finish line, the Double Pumper is a great choice whether you are burning up the street or the quarter mile.
The Double Pumper is designed for use on lightweight vehicles with a manual transmission or an automatic transmission with a high stall and low rear end gears. The Double Pumper features dual accelerator pumps for additional fuel under initial acceleration; mechanical secondaries for great performance; dual feed fuel inlets for constant high volume fuel delivery and a manual choke for easy control of engine warm up.

Don't trust your performance to just anyone. Holley is the only modular carburetor company that has been in business for over 100 years and has powered every NASCAR champion since the 60's.
