It was a straight up side-by-side for the same reason you did, to determine just how close the two cars are. We also ran side-by-sides with my 03 Cobra, but the results were much different.
There is just no getting around the fact the V weighs over 600 lbs more than the Vette and only has 40 horses/14ft.lbs of additional torque to work with. Now, my particular car is factory equipped with the optional 3.15 rear gears which gives me an edge out of the hole, but most of our runs were from a 35 mile roll. The Vette kicks to low gear at that speed, but they run side by side through most of the spectrum - the next advantage is above 140 where the Vette is still holding in third while the V has jumped to its fifth gear. The Vette shifts from third to fourth at 155 mph and is still climbing.
Bottom line is, they are so close it's not worth the energy trying to prove which is better. I'd rather think they are different - not better unless you prefer a retractable hard top, good looks and limited numbers. If you prefer pure sports car ride and feel you are better off picking the Vette. My friend laughed through the whole process, telling me at the end he was happy since he was leaving in the V and I was leaving in the Vette! All of our runs were done at the Castle Air Base outside of Atwater, CA where a large section of the runways have been utilized for several different types of racing events.
Now, my 03 Cobra ran off and left them both, and not by just a little bit......but that's a different story!
