Pontiac Performer Manifold - 326-455

The Pontiac Performer Manifold - 326-455 from Edelbrock is a premium intake solution engineered for serious enthusiasts building or restoring classic Pontiac engines in the 326, 389, 400, and 455 cubic inch range. This manifold exists to bridge the gap between stock restrictive designs and high-performance aftermarket systems, making it the go-to choice for builders who demand both reliability and measurable horsepower gains without exotic porting or complex modifications. Whether you're tuning a street machine, resurrecting a Firebird, or building a GTO for weekend duty, this manifold delivers the intake flow characteristics that modern fuel systems and ignition timing can exploit.

Edelbrock's Performer series uses optimized runner geometry and casting techniques to reduce turbulence and improve fuel atomization across the RPM band, resulting in more consistent combustion and cleaner cylinder charging than original equipment manifolds. The casting is designed to accept standard carburetor mounting (Quadrajet, Holley 4150, and compatible variants) and integrates a water crossover passage for dependable cooling circulation. At 19.76 pounds, the manifold is cast aluminum construction that resists corrosion while remaining light enough to minimize front-end weight bias, a critical factor in handling balance for performance driving. The 15.15 x 24.1-inch overall envelope fits within factory hood clearances on most first and second-generation F-body and A-body platforms, eliminating the need for custom clearancing.

This manifold is ideal for builders upgrading from stock while maintaining bolt-on simplicity and reliability—no machine work, porting, or exotic fuel systems required to see immediate throttle response and mid-range torque improvements. Installation is straightforward on original block gasket surfaces; the manifold accepts all standard Pontiac intake gaskets and fasteners. It pairs exceptionally well with period-correct carburetors, electronic fuel injection retrofits, and modern ignition systems, making it equally at home on a concours restoration or a restomod build. Verify your engine's displacement and original manifold bolt pattern before purchase; this manifold is engineered exclusively for 326–455 Pontiac engines and will not fit Chevrolet or Oldsmobile blocks.
