Dart Heads has just announced their ‘LS Next’ bottom end for GM LS engines, which is the first significant aftermarket bottom end change for the LS series to hit the shelves.

It gets rid of the ‘Y-block’ design and replaces it with standard four-bolt main caps and sump and eliminates the potential for troubles with the LS’ separated crankcase bays, while windage is reduced too giving more power as a result. At the same time, Dart has strengthened the main webs, enlarged the cylinder barrels by .375in.

The iron-block is cast in the USA and more information on this and the company’s vast range of other engine products is available via www.dartheads.com ENDS.
