Edelbrock Victor Jr. 454-O intake manifold is built for competition 396–502 big-block Chevys with large oval-port heads (1975 and earlier). As a single-plane 4150-flange competition manifold it optimizes flow for an 850 cfm carb, producing strong power from 3,500–7,500 rpm and is designed to pair with Edelbrock/Musi Victor Pro-Port CNC heads for high horsepower potential.
