Timing Cover Gasket BBC w/.400 Raised Cam

The Timing Cover Gasket BBC w/.400 Raised Cam from DART is a precision-engineered component designed for big block Chevy engine builds where reliability and proper cam timing clearance are non-negotiable. This gasket addresses a critical sealing point in the engine's front cover assembly, preventing oil seepage that can compromise engine longevity and performance. Whether you're rebuilding a street engine, prepping a high-performance platform, or maintaining a classic big block powerplant, a quality timing cover gasket is fundamental to preventing costly oil leaks and ensuring clean engine bay aesthetics.

Manufactured from composite material at 0.03 inches thick, this gasket is engineered to maintain structural integrity under the thermal cycling and pressure fluctuations inherent in combustion engine operation. The 0.400-inch raised camshaft specification is critical—it accommodates the specific cam profile height of certain big block Chevy configurations, ensuring proper clearance between the timing cover and the cam lobe without compression or binding. The composite construction offers superior resilience compared to paper gaskets, resisting oil degradation and temperature extremes while maintaining a reliable seal across the cover's mounting surface.

This gasket is essential for engine builders and experienced mechanics working on big block Chevy platforms—particularly those running aftermarket or high-lift camshafts where cam-to-cover clearance is a design consideration. Proper installation requires careful surface preparation of the timing cover and block mating surfaces to maximize gasket effectiveness and eliminate micro-leaks. The lightweight construction (0.03 lbs) and compact footprint ensure straightforward installation without added bulk, making it a drop-in replacement for worn or failed OEM gaskets during timing cover service or full engine assembly.
