Speedometer needle

When I purchased my car, 1965 Cutlass F85, the speedometer needle was not accurate. It just kind of dances around above 50. I changed the cable as best as I could given that the drivetrain is not factory; 455 w/ TH400. I am getting the same 'dancing speedometer needle' as before. Is there a way to fix this or does this have something to do with the speedometer itself? I am currently guesstimating my speed with my tachometer. I made a spreadsheet showing approximately what speed I should be driving given the rear gears, tranny gears, and tire size. Thanks for any help.
