SBF Victor Jr. EFI Manifold - 4150 Flange

The Edelbrock SBF Victor Jr. EFI Manifold with 4150 flange is a single-plane competition intake manifold engineered for Ford modular engines, specifically the 4.6L SOHC platform. This naturally finished aluminum manifold delivers optimized air distribution designed to maximize volumetric efficiency across the RPM range, making it the choice for builders pursuing serious performance gains on the dyno and strip.

The Victor Jr. employs single-plane design geometry, which consolidates all cylinders into a shared plenum—a proven approach for peak horsepower when runners can be tuned to match your specific displacement and ignition timing strategy. The 4150 EFI flange pattern ensures direct compatibility with modern fuel injection throttle bodies, eliminating adapter complexity. At 19.5 pounds, the all-aluminum construction keeps rotating mass minimal while maintaining the rigidity required for sustained competition use. Dimensions of 16.75 x 7 x 23.5 inches reflect a compact profile optimized for engine bay packaging on tight builds.

This manifold serves engine builders, racing teams, and enthusiasts upgrading 4.6L platform vehicles—particularly those running forced induction, large-displacement variants, or high-RPM naturally aspirated combinations. The single-plane configuration sacrifices idle quality for peak power, so it's best suited to dedicated performance vehicles rather than street-driven daily drivers. Edelbrock's reputation for CNC-ported precision casting ensures consistent flow characteristics across production runs, a critical factor when dialing in fuel maps and ignition curves.

The Ford modular engine platform has become the standard for late-model restoration, restomod projects, and modern performance applications. Intake manifold selection directly impacts both peak power output and the usable RPM window, making this decision central to any serious build. The Victor Jr. EFI positions itself as a purpose-built solution for competitors and builders unwilling to compromise on airflow efficiency.
