* Engine power and torque: The engine's capabilities ultimately limit how fast the truck can go.
* Transmission gearing: The gear ratios determine the engine's speed at different vehicle speeds.
* Aerodynamics: Air resistance increases significantly at higher speeds, limiting acceleration and top speed.
* Tire size: Larger tires will affect the speedometer reading and slightly alter the top speed.
Therefore, there's no specific RPM or MPH that represents a "factory governor setting." Instead, the Silverado will reach its maximum speed when the engine reaches its maximum power output, or the aerodynamic drag becomes too significant to accelerate further. This top speed will vary slightly depending on the specific engine and transmission combination.
