The Edelbrock adapter plate #2731 converts spread‑bore carburetors to fit Edelbrock intake manifolds that lack a regular mounting flange, giving a clean mechanical interface for retrofit installations. It provides a stout 0.93‑inch thickness to maintain proper spacing and sealing. This compact plate is intended to simplify installation where carb and manifold flange styles differ.
