The Edelbrock Dual‑Quad EFI intake manifold for Mopar Gen II 426–572 HEMI engines is a single‑plane Air‑Gap design intended for 1964–1971 engines operating from about 2,500 to 6,500+ rpm. It uses dual square‑bore 4150‑style throttle body pads with the same spacing and height as Mopar Performance dual‑quad units for direct bolt‑on fitment in shaker‑hood applications, and is compatible with factory cylinder heads while being optimized for Edelbrock Victor Jr. HEMI heads.
