A neighbor had a stock vette of that vintage and body style... Not sure if it was a special edition or not, but it had a LOT of power with the stock motor. He said it was flat-out scary to drive over 100mph due to aero lift so even though it *should* have been able to push past 140mph, he simply didn't drive it fast. He drove maybe 5 miles a month on average, and fired up the motor and ran it up to operating temperature once or twice a month. He was a mechanic and loves cars, so I assume he was planning on keeping it garaged, extremely well maintained, and under 10k miles for a few decades in the hopes that it would become a big dollar collector item. It was a beautiful car, just don't take it over 100.
