Actually more like 1979 or 1980. This was a time when I had just graduated High School and was traveling with dad around the country racing this liquid quarter mile drag boat. Exciting and wonderful days they were! The man in the driver’s seat was the full time driver, not my dad or I. We were close friends with the driver in the boat behind him too, that boat was a Blown Nitro boat, the boat on the trailer (our boat) was a Blown Alcohol engine. That equals some serious difference in power output.
