* Small Block (e.g., 350): These models were generally quicker off the line but had lower top speeds, perhaps in the range of 120-130 mph, depending on gearing and condition.
* Big Block (e.g., 454): Big-block Corvettes had significantly more power and could reach higher top speeds, potentially reaching 140 mph or slightly more under ideal conditions. However, achieving these speeds was dependent on factors like road conditions, tire quality, and even wind resistance.
It's crucial to remember that these are estimates, and the actual top speed of any given 1970 Corvette would depend on its individual condition and modifications. Factory specifications rarely reflect real-world performance perfectly.
