I have a 54' Chevy 3100 that I have decided to begin restoration on. The drive line is all original, transmission is a 4 on the floor, torque tube and original rear end. I believe the engine has been rebuilt, 235 ci. I would like this truck to be able to be a daily driver, or one that I can run up and down the highway with at highway speeds but want to keep the truck as original as possible. Any suggestions as to gear ratio changes or if it would be best to get rid of the original rear end and torque tube? Any advice would be greatly appreciated.
