BB Chevy Intake Set 396-454

The FEL-PRO BB Chevy Intake Set 396-454 is engineered for rebuilding and sealing the intake manifold gasket surfaces on big-block Chevrolet engines spanning 396 to 454 cubic inches. This precision gasket set is essential for anyone performing an engine overhaul, intake removal, or addressing coolant and vacuum leaks originating from the intake manifold interface. Whether you're a seasoned hot rod builder, weekend warrior, or professional mechanic, this OEM-quality gasket kit ensures a leak-free seal that withstands the demands of high-compression and high-performance big-block applications.

FEL-PRO gaskets are manufactured to precise OEM specifications using advanced elastomer and composite materials that resist coolant degradation, oil permeation, and thermal cycling. The BB Chevy Intake Set 396-454 includes all necessary gasket components for a complete intake manifold seal—typically comprising the manifold-to-block gaskets and any requisite coolant passages or vacuum port seals. These gaskets are pre-shaped and ready to install, eliminating the need for custom fitting and ensuring consistent compression across all sealing surfaces. The material composition maintains its integrity across the operating temperature range of modern and classic big-block engines, preventing leakage that can compromise coolant circulation or introduce vacuum leaks into fuel delivery systems.

This gasket set is ideal for engine builds on 396, 402, 427, and 454 cubic-inch big-block platforms commonly found in Chevrolet trucks, muscle cars, and performance builds from the 1960s through 1980s. Installation requires removing the intake manifold, cleaning gasket surfaces to bare metal with a gasket scraper, and applying a thin bead of RTV sealant (especially around coolant passages) before positioning the new gaskets and reinstalling the manifold with proper torque specifications. Always consult your engine's service manual for correct fastener torque sequences to ensure even gasket compression and long-term reliability in both street and competition applications.
