* Gear ratios: The specific gear ratios in the transmission would impact top speed.
* Axle ratio: The rear axle ratio significantly influences top speed. A higher numerical axle ratio (e.g., 3.00:1) will result in a lower top speed than a lower one (e.g., 2.75:1).
* Weight: The car's weight (affected by options and contents) slightly impacts performance.
* Road conditions: Wind resistance, road incline, and tire condition all affect achievable top speed.
* Engine tune: Even slight variations in engine tune could make a difference.
While road tests from the era aren't readily available online with precise top speed figures for this specific configuration, it's safe to say that a top speed in the 75-85 mph range would be a reasonable estimate. However, this is just an educated guess; it would likely be lower than the higher end of that range in real-world driving conditions.
