Built with an all-forged rotating assembly, including 4340 forged steel crankshaft and connecting rods, and forged aluminum pistons, this engine is designed for durability. It is equipped with LSX LS7 aluminum cylinder heads featuring 2.200\" titanium intake valves and 1.610\" hollow, sodium-filled exhaust valves, and a hydraulic roller camshaft. The engine boasts an 11.0:1 compression ratio and is finished with distinctive orange powdercoated valve covers with an engraved LSX454 logo.\n\nThis crate engine requires certain accessories to be purchased separately, including an oil pan and a carburetor with a high-flow intake manifold. The valve covers do not include provisions for mounting ignition coil brackets, necessitating aftermarket or custom relocation brackets. Additionally, the eight-bolt crankshaft flange may require an adapter for compatibility with some transmissions. This engine replaces part number 19355573. It is designed for pre-1976 street vehicles and is capable of approximately 627 horsepower and 586 lb.-ft. of torque.","brand":"LSX","offers":[{"title":"Default Title","offer_id":52662823158072,"sku":"19417357","price":16249.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687500430.jpg?v=1784321458","url":"https:\/\/store.motormia.co\/products\/chevrolet-performance-454-crate-engine","provider":"MOTORMIA","version":"1.0","type":"link"}
