CRATE ENGINES LSX SERIES<br />
The Extreme-Performance Branch of the LS Family Tree<br />
A couple of years ago, GM Performance Parts introduced the<br />
LSX Bowtie cylinder block. Based on the basic design of GM’s<br />
modern LS family of V-8 engines, <strong>it</strong> was designed to give<br />
builders an economical yet exceptionally strong foundation<br />
on which to build extreme-performance engines.<br />
But the LSX block was just the beginning. Our engineers have<br />
been busy developing high-performance engine <strong>com</strong>binations;<br />
and for 2009 GM Performance Parts is proud to introduce the<br />
first two LSX crate engines—the LSX376 and LSX454.<br />
The LSX376 uses the LSX Bowtie block, new LSX forged<br />
pistons and <strong>com</strong>bines them w<strong>it</strong>h the heads and other <strong>com</strong>ponents<br />
of the LS3 engine for an affordable power house. The<br />
LSX454 is a modern interpretation of a classic <strong>com</strong>bination<br />
that over-delivers on the promise of <strong>it</strong>s Big-Block displacement.<br />
These new crate engines offer great performance and<br />
value, but our engineers are just getting started w<strong>it</strong>h LSX<br />
performance.<br />
