The Edelbrock Square-bore Carb to Spread-bore carburetor adapter No. 2697 enables the Edelbrock carburettor of the Performer series to be installed in vehicles with a spread-bore intake manifold (usually GM vehicles that were originally equipped with the Rochester) Quadra Jet carburetor). This kit also works with Chrysler intake manifolds designed for the Thermo Quad carburetor. It contains the necessary parts to adapt the EPS carburetor to the OEM intake manifold. The Edelbrock fuel line kit also includes a heavy duty fuel filter to ensure that the carburetor is supplied with clean fuel.
