Dart LS Next Aluminum Engine Block
Fully redesigned blocks combine the benefits of improved lubrication, increased durability and added versatility. Offered in aluminum or cast iron, blocks use conventional 4-bolt main caps and oil pans, while eliminating the problems associated with the separated crankcase bays. Redesign provides significantly stronger main webs, while allowing the cylinder barrels to be extended .375" into the crankcase for added piston support. Blocks are fully compatible with all stock and aftermarket LS components, and the stock oil pan may be used with Moroso oil pan spacers.
