Holley Performance 300-264 Single Plane Intake Manifold Kit

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 w/manual or electric chokes. These intake manifolds are designed to accept most stock hardware & accessory brackets, but offer performance features; like an updated plenum divider area, a 1" shorter overall height than most single plane manifolds, & a choice of two distributor clamp locations. The isolated design of the air/fuel passages helps to increase cooler charge air density & performance.\nVortec Intake for most popular GM crate engines equipped w/Vortec or Fast Burn Heads including HO engines (like 350 HO), SP Series Engines (SP 350) & ZZ Series Engines (ZZ6).
