{"product_id":"mopar-6-4l-392ci-gen-iii-crate-engine","title":"Mopar 6.4L 392ci Gen III Crate Engine","description":"The Mopar 68303090AC is a 6.4L 392ci Gen III HEMI crate engine designed to elevate performance. This complete engine assembly boasts an impressive 485 horsepower and 475 lb.-ft. of torque, making it a significant upgrade for various applications. It comes with essential components such as a water pump, flywheel and clutch assembly, front sump oil pan, intake manifold with throttle body, fuel injectors, and coil packs.\n\nConstructed with a cast iron block and aluminum cylinder heads featuring Apache Architecture, this engine is built for durability and performance. It utilizes a hydraulic roller camshaft and is the manual transmission version, meaning it does not feature the Multiple Displacement System (MDS) found in some factory applications. The 10.9:1 compression ratio necessitates the use of premium fuel (91+ octane) for optimal power delivery and to prevent detonation.\n\nIt is important to note that exhaust manifolds are not included with this crate engine. Furthermore, while this engine is a powerful option, it may require modifications for installation in Ram trucks or other applications. This unit is not a direct replacement for all factory-equipped 5.7L or 6.4L vehicles, and the installer is solely responsible for executing any necessary modifications. To achieve the advertised power levels at the crank, an engine controller kit (P\/N: 77072451AG or 77072454AI) must also be purchased.","brand":"Hemi","offers":[{"title":"Default Title","offer_id":52688638279992,"sku":"68303090AC","price":7425.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663179773.jpg?v=1784892175","url":"https:\/\/store.motormia.co\/products\/mopar-6-4l-392ci-gen-iii-crate-engine","provider":"MOTORMIA","version":"1.0","type":"link"}
