New LS long blocks from Chevrolet Performance offer builders all the performance capabilities of the complete crate engines, but at a lower cost and with fewer components, for those who want to finish off their engine with their own intake manifold and other accessories. Three new long-block assemblies are available:

LS3 (P/N 19420382) — Based on the production LS3 engine, the engine uses L92-style rectangular-port heads to produce 430 hp and 425 lb-ft. with the production intake manifold and other accessories.
$4999.00



LS376/480 (P/N 19420384) — Mixing the LS3 with the race-bred LS Hot Cam (with .525-in. lift) increases output to 495 hp and 473 lb-ft., when used with the production LS3 intake manifold assembly.
$5350.00



LS376/525 (P/N 19420386) — With an even more aggressive camshaft, featuring a tight 110-degree lobe separation angle, the LS376/525 is designed for high-rpm performance, delivering 525 hp at 6200 rpm and 486 lb-ft. at 5200 rpm, when used with the production LS3 intake manifold assembly.
