{"product_id":"ls3-6-2l-crate-engine-6","title":"LS3 6.2L Crate Engine","description":"The GM Performance LS3 6.2L Crate Engine (MPN 19540155) offers a potent combination of modern technology and uncompromising performance, making it a top choice for enthusiasts and builders of street rods, muscle cars, and resto-mods. Built upon the renowned LS Gen 4 platform, this engine is derived from the C6 Corvette engine family and is engineered for high-revving capability and durability.\n\nConstructed with a lightweight, cast aluminum LS3 block featuring a 6-bolt, cross-bolted main cap design, this engine houses a sturdy reciprocating assembly. It pairs a nodular iron crankshaft with a 3.622-inch stroke with hyper-eutectic aluminum pistons. The high-flowing, aluminum L92-type rectangular-port cylinder heads contribute to a 10.7:1 compression ratio. A high-lift hydraulic roller camshaft, featuring a stock production LS3 profile, provides .551\" lift on the intake valves and .522\" on the exhaust valves, optimizing airflow and enhancing the engine's broad torque curve.\n\nThis crate engine assembly comes complete with essential components, including the EFI intake manifold, fuel injectors, throttle body, water pump, harmonic balancer, and an oil pan. It is configured for factory LS EFI fuel delivery and utilizes a 58X reluctor wheel. For proper installation and operation in project vehicles, Chevrolet Performance recommends using the factory-engineered LS3 Engine Controller and Harness Kit (P\/N 19354328).\n\nIt is important to note that exhaust manifolds and the flexplate are no longer included as part of this crate engine assembly. For specific oil pan requirements, the Chevy Sedan SS specific oil pan is included, but for older vehicles or different applications, Chevrolet Performance's Muscle Car Oil Pan Kit (P\/N 19212593) may be necessary.","brand":"Chevrolet Performance","offers":[{"title":"Default Title","offer_id":52688587522360,"sku":"19540155","price":10504.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687902196.jpg?v=1784891470","url":"https:\/\/store.motormia.co\/products\/ls3-6-2l-crate-engine-6","provider":"MOTORMIA","version":"1.0","type":"link"}
