Does anyone have an idea why my speedometer would be so far off? At 80 indicated I am really only doing like 62 mph.

You may have the wrong speedometer drive gear in the transmission, have you changed out your transmission for another transmission?
Have you changed the rear end or rear end gears?
I know the voices are not real,
but they have some really good ideas.
