The Edelbrock RPM Air-Gap Dual-Quad intake for 289–302 (and related small-block Ford) applications is a dual-plane, taller intake tuned for strong performance from 1,500–6,500 rpm. Its Air-Gap design separates runners from hot valley oil for a cooler, denser charge and improved mid-range power; carb center-to-center measures 6-7/16". The manifold blends dual four-barrel character with a street-friendly idle and throttle response.
