It takes a special intake manifold to present your shiny new aftermarket carburetor as the mountain motor king-of-the-hill. But, the only peak your heavy, restrictive and rusted stock intake manifold is worthy of is the scrap heap. Bring performance to the top of your engine-compartment -peak with an Edelbrock Performer Intake Manifold. This performance, carb-carrying wind tunnel, adds enough horsepower and torque to level hills and the dragstrip playing field. 1-year warranty.
