AMC Performer RPM A/G Manifold - 304-401

The AMC Performer RPM A/G Manifold - 304-401 from Edelbrock is a premium aluminum intake manifold engineered for AMC V8 engines, particularly those in the 304 to 401 cubic inch displacement range. This dual-plane, air-gap design delivers measurable improvement in low- to mid-range torque response, making it ideal for both street applications and off-road platforms where responsive power delivery is critical. Built for operators who demand reliable, proven components that enhance engine efficiency without sacrificing durability or ease of installation.

The Performer RPM A/G utilizes a square-bore carburetor mounting pattern and features Edelbrock's signature air-gap technology, which isolates the fuel mixture from engine heat to improve vaporization and combustion efficiency. The aluminum construction provides excellent thermal management while keeping total package weight reasonable at 22.37 lbs. The dual-plane runner design ensures separate flow paths to upper and lower cylinder banks, optimizing velocity and fuel atomization across the RPM band. Natural finish aluminum resists corrosion and simplifies any future modifications or restoration work.

This manifold is engineered for AMC V8 motors and is compatible with square-bore carburetor systems, making it a direct fit for classic and vintage platforms that demand period-correct or high-performance upgrades. Installation requires basic mechanical competency and standard hand tools; no modification to engine bay or mounting points is necessary on factory or stock-style setups. The manifold's compact dimensions (15 x 7.65 x 24 inches) ensure fitment in tight engine compartments, and the lightweight aluminum design reduces overall drivetrain parasitic losses. Ideal for restorations, weekend warriors, and operators seeking reliable, bolt-on performance enhancements.
