The machined aluminum plate preserves air flow while providing the correct hole pattern and hardware to secure both carburetor and intake reliably. It ships as a complete installation set, including both gaskets, studs, bolts, nuts and lock washers so you have everything to install quickly.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this adapter bridge square and spread bore patterns?\u003c\/h3\u003e\n\u003cp\u003eThe adapter's underside matches the spread‑bore manifold flange while its top deck provides a square‑bore flange for the Edelbrock carb. Internal venturi openings are aligned and smoothed to reduce turbulence between carb and manifold. The result is secure mounting and a direct airflow transition without custom fabrication.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum construction with machined ports for smooth flow\u003c\/li\u003e\n  \u003cli\u003e0.850\" thickness for proper spacing\u003c\/li\u003e\n  \u003cli\u003ePre‑drilled holes and tapped threads for carb studs\u003c\/li\u003e\n  \u003cli\u003eIncluded gaskets seal both square and spread flanges\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill the kit include all fasteners and gaskets I need?\u003c\/h3\u003e\n\u003cp\u003eYes — the SOASEMBE kit is packaged as a full retrofit set so you won’t need to source additional hardware.

It’s ideal for street rods, restorations and performance projects where retaining the stock manifold or a specific carb is preferred over chasing replacement intake pieces.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will this let me mount an Edelbrock square‑bore carb on a Quadrajet manifold?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
