LS376/525 6.2L Crate Engine Assembly

The Chevrolet Performance LS376/525 is a 6.2L, 376 cubic inch crate engine assembly built around the LS3 platform with an aggressive ASA camshaft. This camshaft features a tight 110-degree lobe separation, 0.525" of lift on both intake and exhaust, and durations of 226° intake and 236° exhaust (at 0.050"), delivering a noticeable camshaft idle, superior throttle response, and significant top-end power. This deluxe crate engine assembly produces 525 horsepower at 6200 RPM and 486 ft-lbs of torque at 5200 RPM. It utilizes a cast aluminum block with 6-bolt mains, nodular iron crankshaft, and aluminum LS3 rectangular port cylinder heads with 68cc chambers. The intake fuel delivery system is factory LS EFI. Special notes for installation and operation include: this crate engine requires premium 93-octane fuel, and the exhaust manifolds and flexplate are not included. It uses the Chevrolet SS Oil Pan Assembly, and users should consult with a technical team for suggested oil pan alternatives for specific applications. This engine is developed by GM for pre-1976 street vehicle engine swaps and is not intended for marine usage. A complete ECM/Wiring Harness Kit, programmed and calibrated for this camshaft, is available separately for optimal drivability and performance.
