Overview

The Holley Double Pumper Carburetor 0-4781S is designed for street/strip applications. It includes mechanical secondaries, dual accelerator pumps, a manual choke for precise cold start control, a two-corner idle system, and dual feed fuel inlets for constant high-volume fuel delivery. It also features one timed port, one vacuum port, and one PCV port. This carburetor is intended for lightweight vehicles with manual transmissions or automatics with high stall and low gearing. Each unit is 100% wet-flow tested by Holley technicians to ensure it arrives ready to run. It has a square bore flange bolt pattern and can replace Holley, Edelbrock, Carter AFB, and Autolite style carburetors with a 5 3/16" x 5 5/8" bolt pattern. An adapter (similar to Mr. Gasket #1932) is needed if you have a spreadbore style intake manifold.
