Home > GM Crate Engines > LS Short Blocks > LM7 Short Blocks
The LM7 engines were produced for the 1999-2007 Trucks. These engines can be used for an LS1/LS6 replacement in a cast iron block design, which will support more power (some modifcations to the block/accessories may be required). The LM7 engines are very popular engines to swap into Muscle cars and any other LS Swap vehicle.
