Can anyone tell me how i can get my speedo to be more inline with what is supose to be. I have a 1971 Nova, 350 th tranny. I just replace the dash bezel and . the speedo cable was unhooked so i hooked it back up and when you go down the road like 60 it reads more like 90.
Is there a gear in the tranny that can be changed or why would it be off so bad??????

Any help !!!!!!!
