Any issue putting the 850w fan on with the base alternator?

Running out to check mine!

It is apparently tied to the premium audio group if you have the 8.4 you should have it

180 to 220 is 40 amps (40 amps is bigger than most alternators in the 70s, even early 80s)
The jump from 220 to 240 is only 20 more amps.
I'd definitely try - betting the 220 would keep up easily since your only real change is the fan and the amperage difference between the two fans isn't that much

The draw of that 850 watt fan at 13 volts is 65 amps.
So yeah, you need a different high amp fuse array.
The 600 watt fan would run 46 amps at 13 volts.
You could at max draw pull 20 more amps.

So you get 40 more amps but the fan differences aren't even close to that.

Premium audio group gets the 220 alternator.
The basic Sport with the 7" or smaller radio has the 180 amp alternator. (mentioned "or smaller" because in 2019 you could get a baby radio)

I do have the premium audio group and I do have that same alternator! Cool!

I'd check your fuse array just in case. Pull the the negative battery cables off and separate them, then pull the fender grounds off and separate them. Overkill but it's what I do.

Easy install, all done. 20 min tops.

Some tips:

1. Two A/C lines. They are in a little C valley molded into the fan support passenger side. Grab them from way lower, the braided part, to slightly nudge them out of the way while you clear the fan shroud. Same on reinstall, nudge them back in.

2. Bend top radiator hose away slightly to clear the fan shroud "wing" that holds it in. Same on reinstall, bend it outward.

3. REMOVE: Airbox. 1 10mm bolt on fender, then wiggle it out. Disconnect the air intake hose assembly from airbox and throttle body. Rotate it out of the way, you can leave the connectors on the plastic tube. Just flip it 180 over, lay it on top of the computer. Fan is held in by just two 8mm bolts on each side, near the top. It uses plastic "wings" on the shroud to "clip in" on the lower sides. Only 1 electrical connector, the big boy top passenger side.

4. Tools: 8mm and 10mm socket and some extensions. Nothing else. Trim tool for the top 4 clips that mount the cover to the fan shroud.

5. Fan didn't turn on till about 160F coolant temp. Don't say "oh shit" when it doesn't spin on startup. Isn't supposed to.

Outstanding! Thank you!

Big difference between the two.

The ebay seller finally is back, I asked him about the "New-Other" status. Replies:

Ordered. Will let you guys know.

You are still going to swap yours out? I thought there was no need.

There hasn't been.

I just have OCD.

Over-run??
Seconds i can see but over-run? Not these days. Not even in 1970. Numbers were made to order for specific contract with auto makers.

At that price… ahhh carp… ordering one as well…
