A Legacy of Performance – The LS Engine Family

The LS series revolutionized performance engines in 1997 when General Motors introduced the Gen-III Small Block. Featuring iron-block versions in trucks and the all-aluminum LS1 in the C5 Corvette, this V8 engine family has continuously evolved. GM classifies these engines as Gen III and Gen IV, but enthusiasts worldwide recognize them under the legendary “LS” moniker due to their tremendous performance potential.
