Sorry for the wrong posting location Will, if you could move it I would appreciate it.
The carb is a Rochester Quadrajet 4 B. (rebuilt) running headers and a 2.5" exhaust. RWHP has been dyno'd at 305. I assume I have to weld in the bung just behind the header? There are several different types, which one did you purchase and which one would be best for me?

I'm not sure how a wideband is going to help you tune a car with a carb. It'* really something you'll want an EG analyzer for once in awhile, but not a standalone system like this. Back in the day, we did it by smell.
Thanks for the info Will, and thanks for moving it to the lounge.
I need to set up the carb as best I can get get maximum fuel economy as well as get the best performance I can. Just before I parked it I remember getting an average of 12 mpg. I also have to rebuild the distributor.
