Description:
Designed specifically for Chevrolet big‑block engines (396–502 ci) with oval‑port cylinder heads (1975 and earlier), this Edelbrock RPM Air‑Gap manifold in EnduraShine finish delivers improved throttle response, stronger mid-range torque, and robust horsepower across the 1,500–6,500 rpm range. The Air‑Gap design isolates runners from engine heat to provide a cooler, denser charge. Includes nitrous bosses, rear water outlets, and support for modern accessories—all in a polished satin finish that complements chrome engine bays.
