This Edelbrock choke block‑off is made for Small Block Chevrolet applications using Edelbrock intake manifolds PN 2101, 2104 or 3701. It closes off unused choke passages on those intakes, providing a clean sealing solution when the factory choke is not needed or when converting to a different carburetor setup.
