{"product_id":"zz572-620-deluxe-crate-engine","title":"ZZ572\/620 Deluxe Crate Engine","description":"The Chevrolet Performance ZZ572\/620 Deluxe Crate Engine represents the pinnacle of Big-Block engineering, offering substantial power for performance builds. This engine is constructed with a tall-deck block casting featuring four-bolt main caps and a robust all-forged rotating assembly, enabling it to produce an impressive 621 horsepower and 645 lb.-ft. of torque. High-flow aluminum rectangular-port cylinder heads, with 310cc intake passages and 1.88-inch raised exhaust ports, are paired with a hydraulic roller camshaft featuring 0.632-inch lift and 254\/264-degree duration for optimized airflow. The deluxe package comes complete with an 850-cfm carburetor, HEI distributor, aluminum water pump, and distinctive orange powder-coated valve covers.\n\nInstallation of this engine requires specific considerations. The carburetor is shipped uninstalled due to crate fitment and must be installed by the engine installer. For applications using cast-iron exhaust manifolds, lower head bolts may need to be replaced with shorter versions for clearance. Additionally, a starter and fuel pump are required but not included. The Gen VI tall-deck block is equipped with a machined mechanical fuel pump boss. This engine includes a 14-inch automatic transmission flexplate; however, manual transmission applications will require an internally balanced flywheel. This engine is not intended for marine use.","brand":"Chevrolet","offers":[{"title":"Default Title","offer_id":52687363735864,"sku":"19331583","price":23080.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660684614.webp?v=1784883286","url":"https:\/\/store.motormia.co\/products\/zz572-620-deluxe-crate-engine","provider":"MOTORMIA","version":"1.0","type":"link"}
