* Rear axle ratio: Different ratios were available, altering the speed at a given engine RPM.
* Tire size: Larger tires can slightly reduce top speed.
* Aerodynamics: Any modifications affecting drag would impact top speed.
* Vehicle condition: A well-maintained engine and drivetrain will perform better than a neglected one.
* Road and weather conditions: Obvious factors affecting safe and achievable speeds.
Magazine tests of the time rarely focused on absolute top speed for these cars, prioritizing other performance metrics. Therefore, precise data is hard to come by. The figures given above represent a general consensus based on the car's capabilities.
