* A 1980 Corvette with the L48 5.7L V8 (most common engine): Top speed was likely in the range of 115-125 mph. This is an estimate, as achieving true top speed requires ideal conditions and the car to be in perfect mechanical order.
* 1980 Corvette with the L82 5.7L V8 (optional, higher-performance engine): This engine could likely push the car to slightly higher speeds, perhaps in the 125-130 mph range under ideal conditions.
It's crucial to remember that these are estimates based on factory specifications and road tests of the era. Many factors impact actual top speed, including tire condition, road surface, wind resistance, and the car's overall maintenance. Pushing a car to its top speed also risks damage.
