* Base models with the smaller engines (like the 170 cubic inch six-cylinder) had significantly lower top speeds, likely in the range of 70-80 mph.
* Higher-performance models with the larger V8 engines (like the 289) could reach speeds closer to 100-110 mph under ideal conditions. However, this was also dependent on things like gearing, tire condition, and even the weather.
It's important to remember that these are estimates based on what various sources suggest for the era. Actual top speeds would have varied considerably.
