LSX 376
GM's LSX376 (PN 19171049) is an affordable street performance engine perfect for engine swaps. It combines the strong economical LSX block with production LS3 high-flow, L92-style cylinder heads, camshaft and forged-aluminum LSX pistons. LSX376-logo valve covers distinguish the new crate engine for added pizazz. When equipped with a production LS3 intake manifold and injection system (not included), the LSX376 produces 450 horsepower and 430 lb-ft of torque. It can also be fitted with a carbureted induction system that can be tuned for greater power. The manifold and carburetor are available from GMPP.
