Complete bolt-on big bore power package engineered for late-model touring M8 engines. ⚙️

  • Forged pistons and precision machined billet aluminum parts for strength and reliability.
  • No case machining required for straightforward installation.
  • Independent scavenge sections and debris screens protect the oiling system.
  • Built-in magnet and serviceable passage plugs simplify contamination control.

Precision tappets, hardened tappet cuffs, and a performance cam profile provide improved valve stability at high lift and rpm.

High-performance valve springs and an adjustable pressure relief valve allow tuning for aggressive applications.

Includes chrome pushrod tubes and quick pushrods; not recommended for Tri-Glide or other three-wheel conversions due to lugging characteristics. 🔧
