TTS-787 Tennessee Thunderstix Camshaft – The Best All-Around Cam for GX200, Predator 212, & Clone Engines


The TTS-767 Tennessee Thunderstix is one of the most versatile and proven camshafts for modified 196cc, 212cc, and GX200-based small block engines. Whether you're racing in Limited Modified classes or building a strong mini bike or karting engine, the TTS-767 offers exceptional performance across the low, mid, and top-end powerband.


This cam was originally engineered to maximize performance with stock-size valves and a 25mm carburetor, but it continues to shine with upgraded valve sizes and ported heads. Its ramp profile, duration, lift, and centerline geometry are tuned to deliver balanced torque and horsepower—making it the go-to camshaft for racers looking for flexibility and speed.


Key Features & Performance Benefits

  • Outstanding All-Around Performance – Ideal for builds requiring strong low-end torque, midrange drive, and top-end power without sacrificing throttle response.
  • Proven Design for Modified Classes – Designed for Limited Modified racing with stock or mildly ported heads, but performs even better with larger valves and flow-optimized ports.
  • Balanced Ramp Speed and Timing – Precision-engineered lobes and centerlines optimize cylinder filling, helping your engine breathe efficiently through a broad powerband.
  • Race-Ready for Mini Bikes & Karts – Excellent cam for mini bike racers looking for dependable power across variable track layouts or cruising and racing.
