{"product_id":"zz572-720r-deluxe-crate-engine","title":"ZZ572\/720R Deluxe Crate Engine","description":"The Chevrolet Performance ZZ572\/720R Deluxe Crate Engine is engineered to be the \"king of all Rat engines,\" capable of propelling bracket racers and heads-up challengers into the 9-second range on the drag strip. This fully assembled powerhouse boasts an impressive 720 horsepower and 680 ft-lbs of torque, making it an ideal choice for performance enthusiasts seeking serious power.\n\nConstructed with a brand-new, tall-deck, cast-iron Generation VI block featuring four-bolt main caps, this engine houses an all-forged rotating assembly. The crankshaft has a 4.375-inch stroke, and it is complemented by shot-peened forged 4340 H-beam rods and forged aluminum pistons. The high-flow aluminum rectangular-port cylinder heads feature massive 310cc intake passages and 118cc raised exhaust ports, contributing to its formidable performance.\n\nAt its heart is a unique mechanical roller camshaft with 0.714-inch lift and 278\/282-degree duration specifications at 0.050-inch lift. The engine has a 12.0:1 compression ratio, necessitating the use of 110-octane gasoline, and is described as suitable for limited forays on the street. Installation requires the bolt-on of an included Dominator-style 1090-cfm carburetor, along with a starter and fuel pump, which are not included.\n\nThis ZZ572\/720R engine is also compatible with the Chevrolet Performance TREMEC T56 Super Magnum 6-Speed Manual Transmission and its corresponding installation kit, designed for 427 and 572 Big-Block applications.","brand":"Chevrolet","offers":[{"title":"Default Title","offer_id":52687361802552,"sku":"19331585","price":23166.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662158817.jpg?v=1784883259","url":"https:\/\/store.motormia.co\/products\/zz572-720r-deluxe-crate-engine","provider":"MOTORMIA","version":"1.0","type":"link"}
