The hydraulic roller camshaft provides 0.648-inch lift for both intake and exhaust, with durations of 236° intake and 246° exhaust at 0.050-inch lift. The engine is rated at 627 horsepower at 6300 RPM and 586 lb-ft of torque at 5100 RPM, requiring 92 octane fuel and recommended to operate below 6500 RPM.\n\nThis long block crate engine is delivered without an intake manifold, oil pan, or accessories. A carburetor and high-flow intake manifold are sold separately. Furthermore, the valve covers do not have provisions for mounting ignition coil brackets; aftermarket or custom relocation brackets are necessary. The engine also features an eight-bolt crankshaft flange, which may require an adapter for compatibility with certain transmissions.","brand":"Texas Speed","offers":[{"title":"Default Title","offer_id":52663967449400,"sku":"19417357","price":16249.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687140774.jpg?v=1784331344","url":"https:\/\/store.motormia.co\/products\/lsx-454-crate-engine","provider":"MOTORMIA","version":"1.0","type":"link"}
