19171049 LSX376 Crate Engine
T
he affordable LSX crate engine has arrived!LS3 production parts and the LSX Bowtie block combine for an economical powerhouse in base crate engine form. It makes 450 horsepower with a production-style intake system.
GM Performance Parts takes the economical LSX Bowtie block
and combines it with the LS3’s high-flow L92-style heads and mostly internal components (we swap the pistons for forged parts), to create the affordable, high-revving LSX376 crate engine. It represents the essence of LS performance—exceptional airflow capability in straightforward packaging that delivers huge performance without a power-adder. We deliver the LS376
without an intake manifold (and other accessories). So, whether you top the engine with a carburetor or production-style injection system, it’s suitable for your street rod, ’57 Chevy or ’71 Camaro —be it on the street or strip. Our horsepower and torque ratings are based on using the productionstyle injection system. More power can be realized by swapping
that for one of our carburetor intakes and a well-tuned Holley four-barrel. See page 300 for information on our reference guide P/N 88959384 for installing an LS engine in an older car. NOTE: Due to the number of application variations, the LSX376 crate engine is supplied with a dust shield instead of an oil pan. See the LS Engine Components section for production-style oil pan choices. Also, the LSX376 valve covers do not include provisions for mounting the ignition coil brackets. Aftermarket or custom relocation brackets must
be used. INSTALLATION NOTES
