When comparing the 67 vs 68 Corvette L-88, I can actually see how the 68 was 7 seconds faster to 140 mph. I'd bet up to 110 mph, the cars were nearly identical. Then beyond that, the better aerodynamics of the 68 begin to show. I'd bet from 130 to 140, the 67 was hitting an aerodynamic brick wall, and the 68 cruised to 140 mph much easier.

Aerodynamics play a huge part over 100 mph. Under 100, aerodynamics are more important for fuel mileage, but over 100 mph, the horsepower required to overcome aerodynamics goes up exponentially.
