{"product_id":"zz6-efi-turn-key-crate-engine-5-7l","title":"ZZ6 EFI Turn-Key Crate Engine 5.7L","description":"The Chevrolet Performance ZZ6 EFI Turn-Key Crate Engine delivers 420 horsepower and 445 lb.-ft. of torque, combining modern performance with a classic aesthetic ideal for vintage Chevy vehicles. It utilizes an electronically controlled port fuel injection system integrated into an aluminum intake manifold that mimics the appearance of a traditional carburetor, allowing for the use of a standard air cleaner.\n\nEngineered for high-rpm performance and durability, the ZZ6 features Fast Burn cylinder heads with large intake runners and 2.00\/1.55-inch valves, paired with beehive-style valve springs. An aggressive hydraulic roller camshaft complements the engine's airflow characteristics, ensuring both high-rpm power and smooth low-speed drivability. The engine is constructed with a robust cast iron block featuring 4-bolt mains and a forged steel, shot-peened crankshaft.\n\nThe kit comes with the distributor and damper pre-installed, along with the throttle body, starter, air conditioning pump, alternator, and a single-belt Front-End Accessory Drive Kit. Note that a 12.750\" externally balanced, 153-tooth flexplate is required for automatic transmissions, and an externally balanced flywheel is needed for manual transmissions. This engine is not intended for marine applications.","brand":"Chevrolet","offers":[{"title":"Default Title","offer_id":52687366553912,"sku":"19433044","price":13672.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660684661.jpg?v=1784883308","url":"https:\/\/store.motormia.co\/products\/zz6-efi-turn-key-crate-engine-5-7l","provider":"MOTORMIA","version":"1.0","type":"link"}
