Re: Alternator overdrive pulley. will this one work

I think it should be the standard 17mm, so it should work.
That one on summit is made for the full serpentine belt system though. That's not what 1986 fbodies came with.

Re: stewart stage 2 water pump

IMO easier to get the older short pump and use the pump extensions. Your 86 goes clockwise like all the older ones.

Re: Oxygen Sensor

True. Leaky injectors or leaking fuel pressure regulator will do that.
A couple other conditions can also cause it but is less common.

Leave the gears alone and get a pro Yank 3400 converter. It's expensive but well worth it in performance, and you won't lose any mileage or have to worry about gears or fixing your speedo.
