The Edelbrock square‑bore to spread‑bore adapter #2696 enables installation of a Performer series carburetor on OEM spread‑bore intake manifolds, including stock Quadrajet and Thermo‑Quad applications. The kit contains the required hardware and fittings, and is emissions legal when used with carburetor #1400 on 1980 and older non‑feedback GM V8 vehicles (EO D‑215‑10), simplifying retrofits on classic GM engines.
