* Gear ratios: Different axle ratios were available.
* Tire size and condition: Wider, stickier tires will generally allow for a higher top speed.
* Vehicle condition: Proper tuning and maintenance are crucial. A poorly maintained engine or drivetrain will significantly limit top speed.
* Aerodynamics: Even minor variations in bodywork can affect top speed.
* Road conditions: Headwind, incline, and road surface all play a role.
While some sources might claim a specific figure, it's more accurate to say that a well-maintained 1970 LT1 Corvette *could* reach speeds in the 130-140 mph range under ideal conditions. However, reaching these speeds would require a long stretch of road and significant risk. It's not a number that could be reliably replicated.
