Dart Machinery Introduces Aluminum ‘LS Next’ Block

One year after revealing its remarkable cast iron LS Next engine block, Dart Machinery reduces its mass and announces an aluminum counterpart.

4dDartAlumNextBlock Created from the finest casting materials and weighing 107 lbs, the LS Next was the first aftermarket block to comprehensively address high-performance troubles in the original equipment LS power unit. Laden with innovations, the list of performance upgrades incorporated in the Next block is long.

It was the first to correct rampant internal oil leaks. It was also the first to introduce a stepped bore to maintain oil pressure in the main galley. The first to remove the crankcase skirts, which not only improve windage troubles (eradicating severe turbulence within the crankcase at high revs) but also it allows the cylinders to be extended. “What could be more appealing,” asks its creator Richard Maskin, “Tackling the challenge of windage while at the same time improving ring seal.”

Race engine builders will appreciate extended cylinder bores that allow a 6.125˝ con rod and a four-inch stroke to operate while the piston remains squarely in its bore. They will also be comforted by the introduction of Dart’s proven priority-mains oiling system, 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 7/16˝ 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 9.500˝ and ready for immediate delivery.

Silv-O-Lite Hypereutectic Pistons

The pistons use an aluminum alloy containing 15%-16% silicon, making them stronger than standard cast pistons.

Silv o lite pistons

A set of Silv-O-Lite Hypereutectic Pistons will help make rebuilding the Modular V8 engine in your 1997 to 2020 F-150 more affordable. The pistons use an aluminum alloy containing 15%-16% silicon. This makes them stronger than standard cast pistons with less thermal expansion and more resistance to scuffs and seizures in the cylinder bores. The alloy also reduces ring groove wear and resists cracking in the crown area where operating temperatures are severe. The additional silicon also helps keep heat in the combustion chamber and prevents heat transfer. That’s a lot of piston for the money.
