Chevrolet Performance has released its latest factory-engineered LS high-performance engine: the 376/525 LS3 long block. It blends the racing-derived ASA camshaft with the LS3 6.2L production engine to create the most powerful production-based crate engine in Chevrolet Performance's portfolio, delivering 525 hp at 6,200 rpm and 486 lbs.-ft. torque at 5,200 rpm. (For installation in older vehicles, the engine controller kit part number 19354332 is calibrated specifically for this new engine.) Using the LS3 production engine—the same used in Corvettes and Camaros—as the foundation for the LS 376/525 helped keep the retail price lower; while the ASA camshaft is a proven, power-building component that's been successful in the high-RPM world of Circle Track racing. The ASA camshaft is a hydraulic roller with .525-inch lift on both the intake and exhaust sides, along with 226 degrees duration on the intake side and 236 degrees on the exhaust side. Coupled with a tight, 110-degree lobe separation angle, it helps the engine deliver excellent throttle response and breath exceptionally well at high RPM. The cam also gives the LS 376/525 the most aggressive personality among Chevrolet Performance's growing lineup of production-based high-performance crate engines, which also includes the LS 376/480 and the carbureted LS 376/515. Front-end accessories must be obtained separately, along with the engine controller kit. Chevrolet Performance offers several accessory drive kits to suit a variety of applications; and some installations for older vehicles will require the oil pan changed. Engine specifications: * Power: 525 hp at 6,200 rpm, 486 lbs.-ft. of torque at 5,200 rpm * Displacement: 376 C.I.D., 6.2L * Bore x Stroke: 4.060 in. x 3.620 in. * Compression Ratio: 10.7:1 * Recommended Fuel: 92 Octane * Block: Cast Aluminum with 6-bolt cross bolted main caps * Crankshaft: Nodular Iron * Connecting Rods: Powdered Metal Steel * Pistons: Hypereutectic Aluminum * Camshaft: Steel Hydraulic Roller Tappet * Cam Lift: .525 in.

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.
