The Worst Kept Secret in the Staging Lanes.

In drag racing, there is no second place. You either win, or you load up. The Classic RC "Speed Secret" .23 is designed for the racer who lives life 132 feet at a time. While your competitors are running standard buggy engines, you'll be dropping the hammer on a dedicated 9-Port Big Block monster purpose-built for straight-line domination.

Why a 9-Port? Because airflow is king. The aggressive porting allows this engine to breathe deep and scream to incredibly high RPMs at the top end, while the .23 displacement provides the raw torque needed to launch hard without bogging down. It’s the perfect combination of "hole shot" grunt and "trap speed" glory.

Why You'll Love It:

  • 9-Port Scream Machine: More ports mean more air at high RPM. This engine is tuned to keep pulling hard all the way past the finish line. It doesn't run out of breath; it just asks for another gear.
  • Big Block Torque (.23): Drag cars are heavy, and they need torque to get moving. The .23 size offers significantly more punch off the line than a standard .21, helping you cut better 60-foot times.
  • Drag Racing DNA: This isn't an off-road engine painted black. The timing and crankshaft balance are optimized for maximum acceleration on pavement.

  • Displacement: .23 ci (Big Block)
