Holley's Ultra Double Pumper Carburetors feature all aluminum construction and are equipped with metering blocks and a base plate made from 6061 T6 billet aluminum. Weigh approximately 5lbs. less than a conventional carburetor. The aluminum construction allows the carbs to hold their shine longer than their zinc plated counter parts.
The 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.
