Show original supplier description
The Chevrolet Performance 19435104 LS376/525 crate engine is a powerful 6.2L, 376 cubic inch V8 designed for enhanced performance. Based on the LS3 platform, this engine features an aggressive ASA performance camshaft with 0.525-inch lift on both intake and exhaust, and a duration of 226 degrees at 0.050" intake and 236 degrees at 0.050" exhaust. This configuration provides superior throttle response and significant top-end power, resulting in a "bumpy" camshaft idle characteristic. This 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 main caps and a nodular iron crankshaft. The cylinder heads are aluminum LS3 rectangular port with 68cc chambers, and the valves measure 2.165" intake and 1.590" exhaust. The intake fuel delivery is factory LS EFI. Special considerations for installation and operation include requiring premium 93-octane fuel. The engine uses the Chevrolet SS Oil Pan Assembly; consult with a technical team for alternative oil pan suggestions. This crate engine is not intended for marine usage and is developed by GM specifically for pre-1976 street vehicle engine swaps. Please note that this crate engine does NOT include the ECM controller kit, which is available separately and programmed to match the camshaft for optimal drivability and performance.
