Is this a good location for a wideband? Options

[tornik550]

I have been having issues tuning my carbs. I finally decided to by a wideband air fuel package. I have searched and found several responses. I just want to triple check before I weld the bung. Is the area that is circled a good place to put the bung. I plan on putting it on the front side so it will not be noticeable from the rear- I just didn't have a picture of that side.

The comment about on top is correct due to moisture build up. You could also weld a bung on each side just before the collector flange so each side could be read. I used Bosch 3 wire sensors and GM weather seal connectors so the sensor can be unplugged when needed and the 12 volts help the sender heat up very quickly.

I thought I read somewhere that if the O2 sensor was not powered then it needed to be removed from the exhaust system. Otherwise it would likely be damaged.

GM uses 1 wire sensors everywhere. They are not removed unless defective. 1 wire sensore do not have a heating element like a 3 wire, 5 wire or 6 wire. The 1 wire takes a few minutes for the exhaust to warm it up before it works. I run dual 1 wire O2's. One to the ECU and one to the gauge.
