GM LS Victor Jr. Intake Manifold - 4150/EFI

The GM LS Victor Jr. Intake Manifold by Edelbrock is designed for automotive enthusiasts and professional builders who demand high airflow and responsive throttle characteristics for both carbureted and EFI LS platforms. This single-plane intake manifold is engineered to deliver aggressive, high-RPM performance, making it an ideal choice for those looking to maximize horsepower from modern Gen III/IV LS blocks.

Featuring optimized runner geometry and plenum volume, the Victor Jr. minimizes turbulence and maximizes velocity during the intake stroke, which is essential for effective fuel and air distribution across all eight cylinders. The cast aluminum construction provides a balance of thermal stability and weight savings, while the meticulously ported intake passages ensure consistent distribution for uniform combustion and reliable power delivery throughout the RPM range.

This manifold is particularly beneficial for LS swap builders, naturally aspirated race engine builders, and restomod enthusiasts who prioritize induction efficiency. Its dual-pattern design allows compatibility with both 4150-style carburetors and EFI fuel injection systems, providing flexibility for builders who may want to transition between fuel delivery methods or plan future upgrades.
