paul65,
With your high-pressure 235 engine, and a 3.55 Ring & Pinion conversion (and the associated bearing/gasket/seals/etc kit) and maybe radial tires, you'll easily be able to cruise at 60 mph (1951 3100) on a good highway/Interstate. I did this from Albany NY to Baltimore MD (and, annually to Macungie, PA).
Replace all front end parts (origin speed/design parts are available), and replace spring shackle/pivot/mounting parts, and replace all brake system parts, including lines, and you will drive/stop easily and rest/sleep comfortably.
