On obs stuff ( sold the 88) on mine looks like the only thing that is vacuum operated is the brake booster an blend door...

all the vacuum does is actuate the blend doors.
when i do my hydro swaps i use a super duty E-vacuum pump.
works the HVAC like it should, and the pump only runs when when you need it

I was holding off on the 3g alternator upgrade to delete the vacuum pump, but that's going to happen as soon as I get the axles swapped.
There's really no good excuse to not do it.

are you on V belts or serp?

 

[divemaster5734]

V belt.
I know the resistance of full 160 amp draw can seize a single V belt pulley on a higher rated alternator.
That said, I believe a smaller 130 amp one will work, and that'll double from stock.

I usually have no issues with a 130 amp 3G alternator and V belts on mine. Unless the belt gets a little bit loose. I was having issues with the belt squealing at higher RPM until I bought a Gates green (or whatever it's called) belt. No issues after that.

i wouldnt do a 3g.
not with V belts.
i would 1 wire swap

ive been running a 160A 1 wire for several years

I too run a one wire 130amp Power Master Alternator.
Installed a SW Volt meter in the center of the dash,
I have no tach.

1 wire swap?
Haven't heard of that.

It is a GM single wire alternator.

One wire Alternator has the regulator built in side it.
I rant 2 6ga wires, one to the battery (+)
and the negative connects to a bolt on the back side
of the Alternator, and runs to the battery Neg (-).

Then deep 6 the fender mounted Ford regulator.
