Holley EFI - 300-263

EFI Intake Manifold; Fits Small Block Chevy V8 w/96-02 L31 Vortec Cylinder Heads; Single Plane; 4150 Square Bore Flange;

The new single plane EFI (Electronic Fuel Injection) intake manifold is designed to provide a broad RPM powerband for high-performance street/strip engine applications to a maximum engine speed of 7500 RPM. The manifold is designed to work with 4150 Style Throttle body EFI systems like the Holley 4150 style 112-587 and 112-588. These intake manifolds are designed to accept most stock hardware and accessory brackets, but offer performance features; like an updated plenum divider area, a 1" shorter overall height than most single plane manifolds, and a choice of two distributor clamp locations. The isolated design of the air/fuel passages helps to increase charge air density and performance. The fuel injector bores have back-cut exits in the runners for better fuel atomization. This design points the injectors at an angle to match the intake runner airflow angle. The black coated fuel rails and rail bracket assortment are included with the manifold for any easy installation with the injectors that you choose to use for your combination. Fuel rail designed for maximum throttle lever clearance. Its low profile and single plane design are ideal for Sniper / Terminator TBI installations (dual planes aren't ideal for EFI) Vortec Intake fits most popular GM crate engines equipped with Vortec or Fast Burn Heads including HO engines (like 350 HO), SP Series Engines (SP 350) and ZZ Series Engines (ZZ6).
