Re: RPM vs MPH

At Pomona, I ran 110.66 in my Chevelle first time run Thursday. Tach indicated 7465 RPM at the end. 5.57 gears, Hoosier 9 inch radial slicks, it felt like the engine probably wouldn't go much higher. The formula there is something like 68 RPM per MPH. The real fast 283 cars with 6. 14's at 103-105 must be over 8000. Scary to think about.
