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.
