Intake Manifold - SBC TBI Vortec

The Chevrolet Performance Intake Manifold – SBC TBI Vortec is a single-plane aluminum intake designed for Small Block Chevy applications running throttle body injection systems. This OEM-sourced component delivers optimized air distribution to meet the airflow demands of Vortec cylinder heads, making it the correct choice for builders seeking factory-matched performance without compromise on thermal stability or fuel atomization.

Manufactured in aluminum and finished in natural (bare) form, this intake manifold weighs 23.05 lbs and measures 11.8 x 6.1 x 23.7 inches—dimensions that ensure proper fitment within standard SBC engine bays. The single-plane design optimizes runner length and cross-sectional geometry for consistent cylinder charging across the small block displacement range. The throttle body flange interface accepts standard TBI units, maintaining OEM compatibility and injection timing characteristics. Natural aluminum construction allows builders to ceramic coat, powder coat, or anodize the surface to match specific engine bay aesthetics or thermal management preferences.

This intake is engineered for SBC Vortec engine combinations where fuel injection precision and factory part validation matter. Street applications, crate motor builds, and restoration projects benefit from the pairing of this manifold with Vortec heads—a popular platform combination that delivers modern efficiency with traditional small block simplicity. The OEM Chevrolet Performance lineage ensures engineering rigor and part traceability absent in aftermarket alternatives.

Builders selecting SBC TBI Vortec intake manifolds typically prioritize bolt-on reliability and documented fuel system compatibility. This manifold satisfies both criteria without requiring custom fabrication, carburetor conversion, or port matching—advantages that shorten build timelines and reduce risk on complex engine combinations.
