The Edelbrock RPM Air-Gap Dual-Quad FE intake manifold is intended for 1960‑later Ford FE 390–428 high-performance street engines and complements low/medium-rise or Edelbrock Performer RPM FE heads. Specifically set up for Edelbrock carburetors, it showed strong dyno results in tested combinations and includes a machined breather flange boss; it’s not compatible with 427 Ford Hi‑Riser and Tunnel Port engines.
