In late 1996, Automotive Systems Engineering Division acquired a portion of the remaining Mercury Marine and Chevrolet SPO parts inventory used in the production of the aluminum 350 CID (5.74 L) 4V DOHC LT-5/ZR-1 Chevrolet Corvette engine assembly. Many of the engine assembly components are no longer available from General Motors Corporation. We have limited availability of complete OEM blank serial number production engine assemblies, partial engine assemblies, and assorted accessory parts.
