SBC ALUMINUM BLOCK LS NEXT GEN II FULLY SKIRTED 9.240IN DECK 4.000IN LS R

The Dart LS Next 2 aluminum engine block is a high-performance upgrade for LS engines. It replaces the factory "Y-block" design with conventional main caps and oil pans, which resolves windage and oil control issues, leading to increased power and improved lubrication. Key design improvements include stronger main webs, extended cylinder barrels for better piston support, and a robust 5/8-inch thick full deck for reliable head gasket sealing. It incorporates Dart's priority main oiling system and is compatible with both stock and aftermarket LS components (rotating assemblies, timing covers, rear covers).
