Re: 53 Chevy truck
Yes, there are methods. Usually, speedometer cable driven thimble gears can be exchanged for different driven gear sizes and result in a speedometer indication that is relatively close. However, thimble gears for your transmission are likely no longer available. I had a 1950 3100, 235, "three-on-the-tree" non-synchro trans, probably just like your's.
Another method is an inine gear unit which allows ratio changes. There are several places offering such units. Perform a Google search for "speedometer ratio adapter" and you'll find hundreds.
