{"product_id":"l83-5-3l-v8-long-block-engine","title":"L83 5.3L V8 Long Block Engine","description":"The Chevrolet 5.3L V8 L83 engine, identified by VIN code 'C', is a fully remanufactured unit designed for direct injection and equipped with Displacement on Demand (DOD) and Variable Valve Timing (VVT) for enhanced efficiency. This aluminum block and head engine meets or exceeds OEM specifications and is built for performance and durability.\n\nThe remanufacturing process is extensive, beginning with a complete disassembly and thorough cleaning via hot tanking or thermal cleaning. Each component undergoes magnaflux testing to detect microscopic cracks, followed by visual inspection. Critical surfaces are CNC machined, and new parts such as bearings, pistons, rings, lifters, oil pump, gaskets, valve seals, and freeze plugs are installed. For timing systems, either a new timing chain with tensioners or a new timing belt with a tensioner is fitted, and if applicable, a new water pump is included. Post-reassembly, each engine is SIM tested with pressurized cooling and oil systems and high RPM crank spins to ensure compression and build integrity.\n\nThis engine is explicitly designed for L83 models and will not work for L84 models. It is also not intended for motorhome use. The engine is available as a long block, which includes the engine with an installed oil pump and gaskets. An optional upgrade is available to an OEM Improved Build that includes the oil pan and timing cover with gaskets.\n\nThis engine fits the following applications: 2014-2018 Chevy Silverado 1500 5.3L L83, 2015 Chevy Silverado 1500 LD 5.3L L83, 2015-2020 Chevy Tahoe 5.3L L83, 2014-2018 GMC Sierra 5.3L L83, 2019 GMC Sierra 1500 Limited 5.3L L83, 2015-2020 GMC Yukon 5.3L L83, and 2015-2020 GMC Yukon XL 5.3L L83.
