DA31837211 - LS NEXT BLOCK - 4.125" BORE

4.125" Bore, 9.240" Deck, Short Skirt Block

Part Number: DA31837211

Dart’s LS Next block is the first significant change in the architecture of the LS engine platform. By eliminating the “Y-block” design and utilizing conventional style main caps and oil pans, Dart has addressed the problems resulting from the LS engine’s separated crankcase bays. Windage is greatly reduced, resulting in increased power along with a much stronger main web area.
