The 2696 adapter provides a straightforward mechanical interface so you can mount an Edelbrock four‑hole square‑bore carburetor to stock Quadra‑jet and Thermo‑Quad manifolds without modifying the intake. Built from machined aluminum with a natural finish, this adapter restores correct alignment and porting while keeping installation relatively simple.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this adapter let me use a square‑bore carburetor on a spread‑bore manifold?\u003c\/h3\u003e\n\u003cp\u003eThe adapter physically bridges the mismatch between the four small, closely spaced square‑bore ports and the wider spread‑bore openings. It locates each individual venturi over the matching intake runner and seals with included gaskets to prevent leaks. You retain the original intake and gain compatibility with a wider range of carburetors.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePrecision machined openings to align square‑bore venturis with spread‑bore runners.\u003c\/li\u003e\n  \u003cli\u003e0.850\" thickness for appropriate stack height and flow tuning.\u003c\/li\u003e\n  \u003cli\u003eIndividual venturi ports maintain consistent airflow to each cylinder.\u003c\/li\u003e\n  \u003cli\u003eIncludes gaskets and mounting hardware for a complete installation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat materials and finishes does the Edelbrock 2696 use?\u003c\/h3\u003e\n\u003cp\u003eThe adapter is made from aluminum for a balance of light weight and resistance to corrosion, and it carries a natural machined finish that resists flaking or peeling.
