The A/F is useless unless it is a WB o2. I wouldn't even install it.
You should return it and the volt (unless a track car with no alt).
Get the oil pressure and maybe EGT.
Scoobies love to drink oil and bearing failure usually comes with oil starvation. Keeping a close eye on your oil pressure is one of the best gauges for it besides a WBo2.
