Precision Replacement Cover. The Edelbrock 7788 Valley Cover for GM Gen III LS-Series engines is designed to replace the factory valley cover on specific GM engines converted from electronic fuel injection (EFI) to carbureted setups. It removes the knock sensor bosses that are unnecessary in carbureted applications, providing a tailored fit that enhances engine functionality during the conversion process.
_x000D__x000D_Construction and Appearance. This valley cover is made from natural aluminum using a sand casting process, ensuring durability and a classic finish that complements the engine bay, while standing up to demanding performance conditions.
_x000D__x000D_Installation. Installation is straightforward for automotive professionals experienced in engine conversions. Drilling and tapping may be required if maintaining or converting to the LS-6 style breather setup.
_x000D__x000D_Warranty. The product includes a 12-month warranty to ensure reliability and customer confidence.
_x000D__x000D_Application. Specifically engineered for 1997–2004 GM LS1/LS6 and GM Gen III engines converted from EFI to carbureted; it is not compatible with LS2, LS7, LSX, or other GM Gen IV engines due to design differences.
