Chevrolet Performance 19435108 - LS376/480 Longblock Crate Engine

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. 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. 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. Dipstick, Dipstick Tube, and Steam vent pipe do not come with Long Block engines. Dipstick and tube can be purchased below if using the included oil pan. Check out more steam vent tube offerings here: Steam Vent Tubes
