The affordable LSX crate engine has arrived!
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 the power adder.
We deliver the LS376 without an intake or oil pan and without any front accessories. So whether you top the engine with a carburetor or production style fuel injection system, it's suitable for your street rod, '57 Chevy or '71 Camaro - be it on the street or on the strip.
Our horsepower and torque ratings are based on using the production style fuel injection system.
Due to the number of application variations, the LSX376 crate engine is supplied with a dust shield instead of an oil pan, Any LS style oil pan and pickup that will fit your chassis can be used. Also, the LSX376 valve covers do not include mounting provisions for mounting the ignition coil brackets. Aftermarket or custom relocation brackets must be used.
