NEW L83 5.3 GEN V GM OVERSTOCK ENGINE - 12683694

Description

This brand new, Gen V 5.3 crate engine is the latest in technology from GM. Featuring direct injection and variable valve timing, the L83 engine was the standard V8 option in a half-ton Chevrolet Silverado or GMC Sierra from 2018-2019. If you plan to use it in a 2014 to 2107 vehicle you will need to change the fuel pressure sensor.
While the water pump and vacuum pump are included on this engine, you will have to provide your own alternator, A/C compressor and tensioner.
Engines are new and sold as-is with NO WARRANTY. You, the customer, are responsible for assembly, installation and tuning to achieve peak performance.
