BB Chevy Intake Set 396-454

The FEL-PRO BB Chevy Intake Set 396-454 (Part Number 1290) is a precision intake manifold gasket pair engineered for big block Chevrolet engines ranging from 396 to 454 cubic inches. This composite gasket set delivers reliable sealing at the critical intake manifold interface, where combustion pressure and thermal cycling demand materials that maintain integrity across thousands of operating hours. The 0.06-inch thickness strikes the balance between sealing performance and proper manifold-to-head geometry on classic and modern big block applications.

Cut-to-fit design allows technicians to match the gasket to specific manifold port configurations, accommodating variations in casting between model years and engine variants common in the 396-454 displacement range. The composite material resists coolant degradation and maintains its sealing properties under sustained heat exposure—critical for engines operating at sustained RPM or modified boost levels. The pair format ensures you have coverage for both sides of the dual-manifold configuration typical of big block Chevrolet mills.

This gasket set is the choice for engine rebuilds, manifold replacement, or intake system repair on big block Chevrolet platforms. Whether you're restoring a classic muscle car engine or maintaining a performance big block, proper intake sealing prevents vacuum leaks that degrade idle quality, fuel economy, and drivability. FEL-PRO's reputation in OEM-spec gasket manufacturing ensures this set meets the dimensional and material standards original equipment engineers specified for these engines.

The BB Chevy Intake Set 396-454 is a foundational component for any big block Chevrolet engine work—versatile enough for stock restorations and precise enough for tuned applications where air-fuel ratio control depends on leak-free intake sealing.
