I saw the needle of my 1970 Grand Prix's speedometer somewhere between 130 and 140. My best guess under the conditions was 137. The speedo was at least accurate at 91 according to a dragstrip timing system.
Later, I had a 1987 Caprice ex-police car, with a stock, carbed 350 and "certified" speedometer. It seemed to take forever to creep up to 115 with the pedal floored. The Chevy handled a whole lot better than the GP, but wasn't as fun to drive.
I count myself lucky to have survived that kind of driving, and to have grown up in the great wide open, where you could see the road a mile or more ahead. Where I live now, there would be no way to top out a car without endangering a bunch of other people's lives.
