Dart LS Next aluminum bare blocks are designed from a clean slate approach. They integrate the robust heritage of a traditional Chevy small block with the performance potential of the late model LS engine architecture. By utilizing conventional style main caps and oil pans with LS rotating assemblies and related components, Dart has addressed the LS engine's more noticeable shortcomings on the bottom end—while still supporting high-flow and efficient cylinder heads developed for both the Gen III and IV platforms. Dart LS Next aluminum bare blocks are a real game-changer!
