GEN III CAST ALUMINUM BLOCKS

STRENGTH TO THE NEXT POWER!

QUICK INFO >>>

The ultimate upgrade for adding strength in the Aluminum or Iron LS Next platform is the LS NEXT² upgrade. This offers larger Billet Steel main caps using Ford (2.750”) or LS (2.560”) mains, that feature 1/2” main studs giving superior clamping force for even higher power levels. Blocks come machined to accept fully counterweighted crankshafts & machined for 1/2” head studs.

Features Dart priority main oiling system with provisions for stock oil filter mounting. By utilizing conventional style main caps and oil pans with LS rotating assemblies and related components, Dart has addressed the windage and oil control problems which result from the factory LS engine’s separated crankcase bays.
