Dart Next LS Cylinder Blocks
Total freight cost $175.00 on LS Cylinder Blocks

Dart’s LS Next block has addressed the problems of the LS engine’s separated crankcase bays by eliminating the “Y-block” design and now being able to utilize conventional style main caps and oil pans, windage is greatly reduced, resulting in increased power along with a much stronger main web area.
