Dart LS Next2 9.450" Race Engine Block

Dart LS Next2 9.450" Race Engine Block

The Ultimate cast iron race block which is an ideal candidate for drag racers, circle track competitors, off-roaders, and high performance marine enthusiasts. These blocks 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, and 1/2" head studs. 

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.
