The installation of an O2 sensor is a really good idea. You want the bung welded in as close to the engine as possible for the sensor. I have bungs welded in on my projects for 02 sensors, I just haven't finished any of them yet. I collected the cars and parts when I was working and then I had a stroke so I'm taking a break from them for a while. I had a smog license and dealt with carbs and O2 sensors for 30-years. But I've never had an O2 sensor on a hot rod yet. They are great for dialing the carbs in at idle, cruise and full throttle. Like Bored Stroked said, it's a much better way of tuning an engine than looking at the plugs because you can look at the O2 gauge while you are driving.
