{"product_id":"sp350-357-crate-engine-1","title":"SP350\/357 Crate Engine","description":"The Chevrolet Performance SP350\/357 Turn-Key Crate Engine offers a significant upgrade for various Chevy models, boasting 357 horsepower and over 400 ft-lbs. of torque. This engine is designed for ease of installation, arriving as a turn-key unit with an aluminum intake manifold, Holley 4-barrel carburetor, and pre-installed HEI distributor and balancer.\n\nKey internal components include a forged steel crankshaft and powdered metal connecting rods, paired with cast aluminum pistons. The engine features a hydraulic roller camshaft for improved performance and durability, and it utilizes cast-iron cylinder heads with 64cc chambers. The recommended fuel is premium pump gas, and the ignition timing is set at 32° Total @ 4,000 rpm. The maximum recommended operating RPM is 5600.\n\nAdditional considerations for installation include the requirement for a fuel supply line from the fuel pump to the carburetor. It comes with a 12.750\" externally balanced 153-tooth automatic transmission flexplate; an externally balanced flywheel is required for manual transmission applications. This engine is not intended for marine applications. It is crucial to use a distributor with a melonized steel gear when pairing with long-blocks and partial engines that have steel camshafts to prevent engine damage.\n\nThis engine is intended for use on pre-pollution controlled vehicles, specifically designed for pre-1976 street vehicles or any off-road vehicle. This includes 1965 and older U.S. manufactured California certified vehicles and 1967 and older U.S. manufactured federally certified vehicles.","brand":"Chevrolet Performance","offers":[{"title":"Default Title","offer_id":52687378383160,"sku":"19433034","price":8932.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660192307.jpg?v=1784883469","url":"https:\/\/store.motormia.co\/products\/sp350-357-crate-engine-1","provider":"MOTORMIA","version":"1.0","type":"link"}
