Description

Technical Specs

Designed from a clean slate approach the LS Next Iron block has addressed the shortcomings of the LS platform and is the ideal candidate for hot rod, drag race, circle track, off-road, and high performance marine enthusiasts. 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.
