2 things:
- I don't know if you realize but the narrow band cannot tell you if your mixture is richer than 14.7 BUT NOT how much richer, this means when it shows all the way rich on your gauge, it could very well be 14.0-13.9 - If you cannot afford to get a WB, at least do the old fashioned read the plugs, it does work if done properly. That all being said, these motors are tough and I ran mine lean for a long time without a WB way back in the day and took a long time to blow.
- With your welded diff, are you daily driving? I welded mine and got about a month of daily out of the axles before they broke, I went through about 5 axles before I went LSD - I guess maybe your small tires are not too sticky and that helps? I even stepped it up to a B2600 rear end and welded that - they have bigger axles and they broke too. I remember the fun of limping home on one axle many times.
Definitely like to hear an update on your axles.
