The Ultra Double Pumper Carburetors feature all aluminum construction and are equipped with metering blocks and a base plate made from 6061-T6 billet aluminum. Three different anodized color options (Red, Blue, or Black) allow for a personalized look while maintaining the ultra high strength and durability you get from billet. They weigh in at approximately 5 lbs less than a comparable zinc carburetor. The new Ultra Double Pumper Carburetors have an enhanced fuel curve for optimum performance, with many more features such as aluminum construction; anodized billet aluminum metering blocks and base plate; 4 corner idle for precise idle control; mechanical secondaries for great performance; clear fuel level sight plugs for easy, no mess fuel level adjustments; Ford automatic transmission kickdown for use on popular Ford transmissions; four vacuum ports for all necessary vacuum accessories; and for the first time on a Double Pumper, factory pre-set electric choke for easy, fast cold start-ups. The clean, polished look coupled with Red, Blue, or Black metering blocks and throttle body will certainly set your ride apart whether you are at the show or track. 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 60s.

    • Q:

      I am looking to replace a Holley 4776 600 CFM jetted Double Pump, Mechanical P&S, Manual Choke, dual fuel feed sitting on a Performer manifold on a 70 Vette. I'm looking at your Holley 600 with same make-up except electric choke using the stock 70 vette air cleaner and clearance height. Thoughts/recommendations?

        As for the carburetor, use this tool to see what options Holley have with the features you are looking for. Maybe you don't actually need a double pumper and Vac secondary would be better. Then search the compatible carburetor in our website. Here is the link to the tool:

        This part is universal and not a direct fit. Slight modification may be required for proper installation.

        This is a universal carburetor so an adapter plate may be required to get this to use on your Camaro.

        To adequately not under or oversize a replacement carburetor you always need to check your vehicles original equipment issued. Then you can select the correct replacement without losing any performance. It has been my experience with most Holley carbs that they are fairly generic and will fit with there after market accessories such as an adapter plate.
        Good Luck and I hope this helps
