    Idle-5500 RPM Power!

    Performer manifolds are dual-plane, low-rise intake manifolds with a 180° firing order and a patented runner design that delivers outstanding performance. This patented design greatly improves torque over a wide rpm range, especially off-idle through 5500 rpm. Provides crisp throttle response. Most Performer intakes are 50-state legal, when used with the correct carburetor and in the correct application.

    Note:To insure proper manifold to cylinder head sealing, Edelbrock recommends using an embossed intake gasket like Fel-Pro's Printoseal or Mr.Gasket's Ultra Seal. Fel-Pro's Perma Torque Blue and other similar gaskets do not compress well when used with an aluminum intake manifold and may cause vacuum leaks.
