Intake Manifold 1957-1986 262ci-400ci, 1987-later with Aluminum Heads
Part Number: 300-261
The 300-261 intake manifolds are designed for square-bore carburetor applications on 1957-86 262-400cid Small Block Chevrolet engines and SBC engines equipped with 1987-91 L98 aluminum Corvette cylinder heads (non-EGR applications). Also, these manifolds will work with any SBC engine equipped with aftermarket cylinder heads, as long as they have a standard port flange opening and mounting bolt locations. 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 height than the 300-25 manifold, and a choice of two distributor clamp locations. The isolated design of the air/fuel passages helps to increase charge air density and performance.
Features and Benefits
• Power band: 2500-7500 RPM
• Square Bore Carburetor Mounting Flange
• Isolated Water cross-over
• Port Size: 1.92” height 1.20" width
• Height: Front 4.18", Rear 5.28"
• Single Plane with Isolated Plenum
Modification to the valve covers may be required when this manifold is used with some types of cylinder heads.
