I owned a 66 C-20 for 17 years and drove to work everyday. Also used it with a camper and went everywhere. The first thing I did was replace the 3 speed with a 3 speed overdrive. I later replaced the 292 with a 327 and installed power steering and a brake booster with a dual MC. There are many more options available today but it was more than adequate for the time.
