Description

If you're building a serious LS platform engine for drag racing, circle track competition, or high-performance marine duty, you need a block engineered to handle extreme cylinder pressures and sustained power. The Dart SHP LS Next PRO delivers the structural foundation required for forced induction, nitrous oxide, or high-RPM naturally aspirated applications—without compromise. This 220 BHN cast iron block combines factory LS compatibility with purpose-built reinforcements that separate race-ready engines from bolt-together builds.

Key Features:

  • Superior 220 BHN cast iron
  • Steel 4-bolt main caps
  • Upgraded ARP main studs
  • Full skirt design
  • Priority main oiling system
  • 8-counterweight machining
  • 6-bolt per cylinder capability
  • Thick deck construction
  • Siamese cylinder bores
  • 4.125" bore, 9.240" deck height
  • Lifter oil crossover with restrictor
  • Stock and aftermarket filter provisions
  • 1-piece rear seal
  • Bare block, ready to machine
  • GM LS-series compatible

Helps keep cool, works great!

Bought the dual pass Allstar radiator for my build, and it’s been solid. Keeps the engine running cool even on the hottest days no complaints here!
