LSX376 — 19171049
GM Performance Parts takes the LSX Bowtie block
and combines it with the LS3’s L92-style heads
to create the LSX376 crate engine. This engine
will be delivered without an intake manifold
(and other accessories), but can be fitted with
either a carburetor or production-style
injection system to make it suitable for your
street rod, ’57 Chevy or ’71 Camaro.
