QUALITY STRENGTH PERFORMANCE SINCE 1981<br />
FULL SKIRT DESIGN<br />
QUICK INFO >>><br />
Designed from a clean slate approach the LS Next Aluminum block has<br />
addressed the shortcomings of the LS platform and is the ideal candidate<br />
for hot rodders, drag racers, circle track competitors, off-roaders, and high<br />
performance marine enthusiasts.<br />
Features <strong>Dart</strong> priority main oiling system with provisions for stock oil filter<br />
mounting. By utilizing conventional style main caps and oil pans with<br />
LS rotating assemblies and related components, <strong>Dart</strong> has addressed<br />

engine’s separated crankcase bays.<br />
