Chevrolet Performance's 525 RLB is based on the LS engine family and is like the 6.2L CT525 but sold as a sealed long block for universal racing sanctioning bodies. The high-revving 525 RLB crate engine is assembled with strong forged pistons and heavy-duty connecting rod bolts designed to support its performance capability and enhance its durability. With its deep-breathing LS3 rectangular-port cylinder heads, it is a combination rated at 533 horsepower at 6,600 rpm and a strong 477 lbs.-ft. of torque at 5,200 rpm, when used with a 4-barrel carburetor and intake manifold, per Chevrolet Performance testing. The engine assembly comes with coil-on-plug ignition and an SFI-certified balancer, along with a 6-quart racing oil pan and more. All that's needed to complete the assembly is an induction and ignition system—and those components are also available from Chevrolet Performance (*refer to installation information noted below). *Installation Notes: Requires addition of induction and ignition control system, starter, fuel system, exhaust system and front accessory drive system The 6-quart racing oil pan is designed to clear most GM rear-steer chassis with stock engine location. The long block is designed for universal racing sanctioning bodies. It is not intended for street use. The 525RLB does not included water pump, intake manifold or factory exhaust manifolds. Chevrolet Performance Racing Long Block engines include factory-installed anti-tampering seals.

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.
