Beschreibung
Chevrolet Performance 19435110: LS3 LONG BLOCK ASSEMBLY - 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:.
