Performance Intake Manifold. The Edelbrock 1963-72 Fullsize Ford-Mercury Edelbrock 7521 289-302 Ford RPM Air-Gap Manifold is engineered for small-block Ford V8 engines, specifically tailored to optimize power in the 1,500 to 6,500 RPM range. It improves engine efficiency by reducing heat transfer to the incoming air charge, making it ideal for hot rodders, street machines, and bracket racers seeking enhanced horsepower and throttle response.
_x000D__x000D_Construction and Appearance. This intake manifold is crafted from lightweight yet durable aluminum, featuring a satin finish that offers both corrosion resistance and a clean, professional look under the hood. Its design incorporates an open Air-Gap under the plenum to keep intake runners cool, and it includes larger runners for better volumetric efficiency on larger displacement engines.
_x000D__x000D_Installation. Installation is straightforward with no drilling required, suitable for experienced and professional enthusiasts. Proper torque application is essential, including the use of hardened washers with intake bolts to prevent damage. Use high-temperature RTV sealant for end seals instead of end seal gaskets.
_x000D__x000D_Warranty. The product carries a 12-month warranty for peace of mind and quality assurance.
_x000D__x000D_Application. Fits small-block Ford V8s with 302, 331, or 347 cubic inch displacements. It does not fit 255 CID V8 engines and is not recommended for 289 Cleveland models.
