Whether you're looking to build a reliable engine for towing and hauling or want the foundation for a high-performance build, the Chevrolet Performance 6.0L 366 C.I.D. L76 Remanufactured Crate Engines are a great starting point and at a more affordable cost. These crate engines boast a number of features and benefits. Each engine is tested to meet or exceed GM's original equipment specifications. Additionally, every component is inspected and replaced if necessary. As a result, these remanufactured crate engines provide excellent value and dependability. Specific information (instructions): The replacement crate engines are built with two different designed oil pans. Differences are the first design oil pan has threaded hole for oil level sensor; the second design oil pan is without hole for the oil level sensor. Transfer oil pan from original engine or procure new, if required. For C/K Trucks, G-van applications, the oil pan on the replacement engine has been upgraded with a new oil deflector (shield) installed over a new oil pressure relief valve. If transferring the original oil pan to the replacement engine transfer these new components to that oil pan. --Transfer crankshaft balancer, crankshaft sensor, camshaft sensor, sensor wiring harness and bracket from original engine or procure new. --Install new crankshaft balancer bolt that is included with engine assembly. --Refer to instruction sheet for general/detailed information and instructions on components that are required to be transferred from the original engine assembly or procured new. --Transfer crankshaft balancer, crankshaft sensor, camshaft sensor, sensor wiring harness and bracket from original engine or procure new. --Install new crankshaft balancer bolt that is included with engine assembly. The replacement engine is built with a first or second design oil pan. The first design pan has a threaded hole for applications equipped with an oil level sensor. The second design oil pan is for applications that do not use an oil level sensor; no threaded hole. Transfer oil pan from original engine or procure new, if required. The replacement engine is built with first or second design valve rocker arm covers. The first design valve covers do not use quick connect PCV tubes. The second design valve covers use quick connect PCV tubes. Transfer valve covers from original engine or procure new, if required. The replacement engine may use rivet-type plugs in place of the coolant air bleed covers located at the top rear of each cylinder head. In applications that contain the rivet-type plug, it is not necessary to install the coolant bleed covers. For LS4 Applications, transfer the A/T flywheel/flexplate locator that is pressed into the rear hub of the crankshaft from the original engine or procure new. For C/K Trucks, G-van applications, the oil pan on the replacement engine has been upgraded with a new oil deflector (shield) installed over a new oil pressure relief valve. If transferring the original oil pan to the replacement engine transfer these new components to that oil pan. For 2007 Cadillac Escalade and GMC Yukon Denali applications w/6.2L L92: Engines prior to April 2006 were built with AFM (Active Fuel Management) hardware components, but the AFM system is not enabled on the 2007 L92 engine. The replacement engine does not contain the AFM hardware; it includes a valley cover that is used in place of the VLOM (valve lifter oil manifold). Do not transfer AFM hardware to replacement engine. When performing an engine replacement on a L92 engine that was originally equipped with AFM hardware, the VLOM electrical connector must be removed from the wiring harness. Included Engine Content: * Engine Block * Pistons * Crankshaft * Connecting Rods * Cylinder Head * Camshaft * Front Cover * Housing, Cr/Shf Rear Oil Seal * Valve Cover/Cam Cover * Valve lifter Oil Manifold (VLOM) * Oil Pan
