Carb Adapter Plate

The WEIAND Carb Adapter Plate (MPN 9006) is a precision carburetor adapter engineered to bridge incompatible intake manifold bolt patterns and carburetor flange designs. As a seasoned mechanic, you know that engine swaps, manifold upgrades, and carburetor conversions often demand a reliable transition component to ensure proper fuel delivery and air sealing. This square-bore-to-spread-bore adapter eliminates the guesswork, allowing you to pair premium carburetors with manifolds that would otherwise require costly modification or replacement.

Constructed from durable aluminum and finished in natural (bare) state, the adapter plate measures 6.85 × 7.25 inches with a thickness of 0.063 inch—a specification that balances structural integrity with minimal height addition to your intake stack. The open design (no integral fuel bowl or bowl mounting provisions) keeps weight down to 0.38 lbs and allows unrestricted air flow through the bore. Gaskets are included, eliminating the need for separate sourcing and ensuring an immediate, leak-free seal between carburetor and manifold. This thickness and material choice are critical: too thin, and you risk warping under clamp pressure; aluminum conducts heat efficiently, reducing hot spots that can cause vapor lock in fuel lines.

Whether you're restoring a classic muscle car, upgrading a street engine, or completing a non-original carburetor installation, the WEIAND adapter plate solves real-world fitment challenges without compromising airflow or requiring fabrication. Installation is straightforward—sandwich the included gasket between the manifold and carburetor flange, secure with standard hardware, and verify fuel line and choke clearances. This adapter is ideal for hot rodders, engine builders, and shade-tree mechanics who demand bolt-on solutions that maintain OEM-level reliability and performance.
