{"product_id":"quicksilver-value-series-5-7l-longblock-engine-assembly","title":"Quicksilver Value Series 5.7L Longblock Engine Assembly","description":"The Quicksilver Value Series Longblock is a new, 8-cylinder, 5.7L (350 V-8) marine engine assembly designed for left-hand standard rotation. It is constructed with 100% new content and features a cast iron block with thicker castings for quieter operation and enhanced durability, especially in saltwater. This engine replaces most 1996-2015 5.7L Gen+ marine engines that use an 8-bolt intake manifold and a standard marine camshaft for a 4600-5000 RPM range. It does not include provisions for a mechanical fuel pump.\n\nKey components include a nodular iron crankshaft, single-piece rear main seal, roller camshaft, marine oil pan, high-flow oil pump, and harmonic balancer. The Quicksilver cast iron cylinder heads come with hardened seats, screw-in studs, and Black-X valves, which reduce valve wear by 42% compared to traditional stainless steel valves. This longblock is suitable for carbureted or throttle body fuel-injected (TBI EFI) sterndrive and inboard engines from 1996-2015, as well as specific 350 Mag MPI engines from 2001-2004.","brand":"Quicksilver","offers":[{"title":"Default Title","offer_id":53735288373560,"sku":"8M0187365","price":8111.02,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/847433779.jpg?v=1793796339","url":"https:\/\/store.motormia.co\/products\/quicksilver-value-series-5-7l-longblock-engine-assembly","provider":"MOTORMIA","version":"1.0","type":"link"}
