M177 Short Block — 1,500HP Forged Build
The M177 Short Block is a fully built foundation for extreme horsepower builds on the Mercedes-AMG M177 4.0L twin-turbo V8.

Forged Piston Specification
Every YPG M177 Short Block ships with ceramic and Teflon-coated forged pistons rated to 1,500HP+ — CP-Carrillo or equivalent tier-1 sourcing:
- Ceramic-Coated Piston Tops — Thermal barrier coating on all 8 piston crowns reduces heat transfer and detonation risk at high boost. Standalone coating service (Swain Tech, Calico) runs $200–400 per set.
- Teflon-Coated Skirts — Anti-friction coating reduces piston-to-wall contact friction and wear under sustained high-RPM operation.
