Dart Unveils Aluminum “LS Next” Engine Block
Dart Machinery is again playing ball in the big leagues thanks to yet another aftermarket LS engine block, only this one is aluminum and weighs 108-pounds less than its steel counterpart. The LS Next block is said to address downfalls found in the stock blocks, like high-RPM windage concerns and it features such upgrades as extended cylinder bores that not only accept 6.125-inch connecting rods and a 4-inch stroke, but also resolve ring-sealing problems on long-stroke combos. The new block also features a priority-mains oiling system.
Here’s what Dart has to say about its LS Next block:
which ensures lubrication reaches the crank and rods first.More encouragingly, standard LS components are compatible with the Next block. Featuring a standard deck and head bolt pattern, the LS cam and stock oil pump and all other components are accommodated. Steel main caps are featured with 7/16in bolts properly splayed to take anchor in the safety of the block’s more reinforced areas.Other key innovations that define the characteristics of this new aluminum engine are the installation of Darton’s finest nodular-iron cylinder sleeves. And to facilitate a full kick-out oil pan the block is equipped with dual starter mounts, allowing the starter to be
mounted either side. Dart’s aluminum Next engine block is available in deck heights of 9.240 to 9.500in and ready for immediate delivery.
