GM 364 C.I.D. LC8 Long Block Crate Engines

The LC8s were 6.0L Gen 4 small block engines used in GM trucks and SUVs between 2011 and 2019. They are unique among the Gen 3 and Gen 4 engines in that they are the only ones designed to operate on gasoline and LPG or CNG fuels. We purchased the last of these new in the box from a large fleet company’s inventory. This means we cannot extend a warranty from the manufacturer, however we do offer our standard 90 day handshake guarantee. This is a last chance opportunity, once they’re gone we won’t be able to order more so grab one while you can!
