This was no ordinary engine — it was a radical prototype born from innovation and rebellion. Built in secrecy, tested by legends, and banned before it could dominate, the 427 Mystery Motor stands as the missing link between Chevrolet’s early 409 W-series and the iconic Mark IV “Rat Motor” that conquered racing in the mid-’60s. 🔧 Inside The 427 Mystery Motor: Advanced wedge-shaped combustion chambers with canted valve heads for “hemi-like” airflow High-compression pop-up pistons & heavy-duty connecting rods from the legendary Z11 427 Prototype aluminum high-rise intake for maximum breathing at high RPM Unique internal fuel and cooling systems tuned by Smokey Yunick himself Developed by GM engineering masterminds Dick Keinath, Bill Howell, and Zora Arkus-Duntov, this engine was Chevy’s covert weapon in response to Ford’s dominance.
