Holley 300-264 Chevy Small Block V8 with L31 Vortec Cylinder Heads SBC 4150 Single Plane Intake Manifold Small Block Chevrolet

The new single plane 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 carburetor-mounting pad is designed to accept all stock or aftermarket square-bore carburetors with manual or electric chokes.

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 inch 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 cooler charge air density and performance.

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).
