MERCEDES-BENZ ORIGINAL AMG M117 ENGINE 6.0L V8 – TESTED & GUARANTEED

The Original AMG M117 engine is one of the most iconic and sought-after Mercedes-Benz powerplants, built during the golden era of AMG performance engineering. Known for its robust V8 configuration, hand-built precision, and unmatched durability, the AMG-tuned M117 represents a rare piece of automotive history. Designed for legendary Mercedes models like the W126 S-Class, SEC Coupes, R107 SL Roadster, and W124 E-Class AMG conversions, this engine is a collector’s dream and a performance enthusiast’s perfect upgrade.

Key Features

• Legendary Heritage: Designed and hand-built by AMG’s master engineers before the brand became Mercedes-AMG, the M117 engine is a symbol of racing pedigree and bespoke performance.
• V8 Powerhouse: A 5.0L or 5.6L naturally aspirated V8 configuration (depending on variant), delivering raw, linear power and a spine-tingling exhaust note that defined AMG’s early reputation.
• Motorsport DNA: Engineered for dominance in touring car racing, this engine powered the iconic Mercedes-Benz 450 SLC AMG and 500 SEC AMG “Hammer,” setting benchmarks for speed and endurance.
• Handcrafted Precision: Each unit was assembled by hand, featuring AMG’s signature upgrades like high-performance camshafts, forged internals, and optimized airflow for unmatched responsiveness.
• Exclusivity: Rare and highly sought-after, original M117 engines are increasingly scarce, making this a prized centerpiece for classic car restoration or display.

Technical Specifications

• Displacement: 5.0L (M117.968) or 5.6L (M117.975) modified to 6.0L 24 valves
• Configuration: 90° V8, SOHC
• Power Output: Up to 375 HP (post-tuning for racing variants)
• Torque: ~400–450 Nm (dependent on configuration)
• Fuel System: Mechanical fuel injection or later KE-Jetronic.
• Engine: The 6.0-liter V8 engine is based on the M117 architecture, but AMG added their own 4-valve cylinder heads and camshafts to increase output dramatically. The entire block was professionally cleaned, resurfaced, and rebuilt to precise AMG specifications, with every critical component inspected and measured.
• Performance: These AMG-modified engines produce around 380 horsepower and significant torque, offering a level of performance far beyond the standard W126 models.
• OEM parts: Many original equipment manufacturer (OEM) and AMG-specific parts were used to ensure the engine’s authenticity and performance. Notable items replaced include:
  • New timing chain, tensioners, and guides
  • All new gaskets and seals, including the crucial valve cover and head gaskets
  • New piston rings and bearings throughout the engine
  • Refurbished or new camshafts, solid lifters, and springs, specific to the 4-valve AMG heads
• Engine bay modifications: This powerful 6.0L engine required modifications to the engine bay, specifically “hammering” of the front bulkheads, for the DOHC heads and performance headers to fit.
