* Engine: The 1984 Bronco offered various engine options (e.g., inline-6, V8s of different sizes). A larger, more powerful engine would have a higher top speed.
* Transmission: Automatic or manual transmissions also affected performance and top speed.
* Axle Ratio: Different axle ratios were available, impacting acceleration and top speed. Lower ratios prioritized torque for off-roading at the expense of top speed.
* Weight: Added weight from accessories, cargo, or passengers would reduce top speed.
* Condition: The overall mechanical condition of the vehicle played a significant role.
While a specific number can't be given, you could reasonably expect a top speed in the range of 65-85 mph for most configurations. However, this is just an estimate; the actual top speed could be higher or lower depending on the factors listed above.
