GM introduced the LS3 in 2007 for use in the 2008 to 2013 Corvette lineup. The LS3 was later put into service in the 2009 to 2015 Camaro SS and the short-lived Chevrolet SS from 2015 to 2017.

The LS3's displacement is 6.2 liters, which is slightly larger than the classic 5.7-liter (350-cubic inch) small block that powered GM vehicles for over three decades.
