If you ever read any magazines that do top speed tests, they usaually point out that most car's speedometers are very inaccurate at the upper end of the spectrum, usually on the optimistic side... (speedo reads higher than the car's actual speed) Regardless, any time you get over about a buck twenty things start going by awefully fast... I remember riding in bkh's fathom green Yenko Camaro on the highway at SCR1 doing some sort of crazy speed with the factory tach burying itself repeatedly with each shift on its way to the top end... That L-88 would scream!
