It is intended as a performance foundation for builders who need more architecture and strength than a production-style block can provide.\u003cbr\u003e\u003cbr\u003eAluminum construction, performance grade type, 9.76 inch deck height, 4.125 inch cylinder bore diameter, .904 inch lifter bore diameter, and a raised cam centerline intended to allow larger stroke. This makes it a strong starting point for LS builds where deck height, rotating assembly planning, and machining precision are central to the final combination. The tall-deck format is best approached as a precision engine-building component, with machining and assembly decisions planned around the final combination.","brand":"Edelbrock","offers":[{"title":"Default Title","offer_id":58173511958912,"sku":"54901U-904","price":6904.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0982\/9390\/7840\/files\/RHS_54903U-904_BLOCK__20Standard_20Deck_200.904_V1_eb73edf9-d452-4f0f-a159-30d8d20ef504.jpg?v=1779998537","url":"https:\/\/modridge.com\/products\/edelbrock-engine-block-54901u-904","provider":"Modridge","version":"1.0","type":"link"}
