Chevrolet Performance LS3 Long-Block Crate Engine 19434644

This new LS long block from Chevrolet Performance offers 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.

LS376/480 (P/N 19434646) — 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.

Each new long-block assembly is delivered without the intake manifold, throttle body, fuel rail, injectors, exhaust manifold, or other accessories. Mix and match the parts to take your LS performance engine to the next level.
