It’s based on the LS3, but adds our aggressive ASA camshaft to expand the performance range, particularly at high rpm, resulting in 525 horsepower and 486 lb.-ft. of torque.\u003c\/p\u003e\n\u003cp\u003eThe ASA camshaft is a hydraulic roller with .525-inch lift on both 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.\u003c\/p\u003e\n\u003cp\u003eYou’ll need tuning to make the most of the engine in a late-model GM vehicle. If you plan to use the LS376\/525 in a vintage car, you’ll need the controller kit P\/N 19354332, which includes the throttle pedal to match its electronically controlled throttle body.
