Why the Dart LS Next block?

The LS Next block is the first significant change in the bottom end architecture of the LS engine platform. By eliminating the “Y-block” design and utilizing conventional style main caps and oil pans, (stock pans can be used with Moroso oil pan spacers) Dart has addressed the problems resulting from the LS engine’s separated crankcase bays. Windage is greatly reduced, resulting in increased power and improved lubrication.

This design change led to several additional improvements. The main webs are significantly stronger because the bay to bay breathing windows are eliminated in Dart’s design. Deleting the windows also allows the cylinder barrels to be extended by .3750” into the crank case, providing greater piston support at the bottom of the stroke. Two standard bore sizes are available, 4.000” and 4.125”. Maximum bore of 4.220” for iron and 4.165” for aluminim, or optional Darton M.I.D. sleeve kit allowing up to 4.220” bore.

All stock and aftermarket LS components can be utilized. Conventional style 4-bolt steel main caps are used. A 5/8” thick full deck design is utilized for superior strength, with six head bolts per cylinder to provide secure clamping. Dart’s priority main oiling system ensures high rpm reliability and includes provision for oil restrictors in the lifter valley.

Recent customer that brought in a LS2 for a rebuild: “Seeing them side by side, the Dart block is clearly a better piece - even from a distance.”
