The innovative single-plane intake manifold is expertly engineered to deliver a broad RPM powerband, ideal for high-performance street/strip engine applications with a maximum engine speed of 7500 RPM. The carburetor-mounting pad is meticulously crafted to accommodate both stock and aftermarket square-bore carburetors, whether equipped with manual or electric chokes.
\n\nDesigned for versatility, these intake manifolds seamlessly integrate with most stock hardware and accessory brackets while offering performance-enhancing features. Notable attributes include an updated plenum divider area, a reduced height of 1" compared to the 300-25 manifold, and the convenience of two distributor clamp locations. The isolated design of the air/fuel passages contributes to heightened charge air density and overall performance.
\n\nThe 300-261 intake manifolds are tailored 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). Additionally, these manifolds are compatible with any SBC engine featuring aftermarket cylinder heads, provided they have a standard port flange opening and mounting bolt locations.
