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

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" 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.

Features:

• Single plane design with isolated plenum to keep the air charge cooler
• 4150 square bore mounting flange to adapt most aftermarket throttle body designs
• Power band: 2500-7500 RPM
• Height: Front 4.23", Rear 5.33"
• Port Size: 2.05" height 1.02" width
• Small Block Chevrolet 262-400 cid engines equipped with 1996-2002 (L31) Vortec cylinder heads (non-EGR applications)
