does it have to be at your standards?

Hey Brendan, Andrew (87 F-150 I6) gave me a link to a place that sells true high output alternators. I haven't tried them yet, but I think Andrew has one. Maybe he can chime in or you can send him a PM. These actually put out high amps even at idle, so they are higher performance alternators than the stock units.

My new alternator arrived today and I still have my original 3G alternator so I snapped some pics for size comparison:
Today it was 57* out today - tomorrow (install day) it may crack 30*.... figures.

Removal is super easy:
1. Unbolt 10mm nut from 12v+ supply on back of alternator & remove wire
2. Unplug harness from alternator
3. Use 1/2" breaker bar to loosen and remove serpentine belt from alternator pully
4. Remove three 13mm bolts
Now, since this is a bigger case, you have 2 options:
A) install 1/8" thick worth of spacers/washers between the bracket and alternator
B) grind the bracket to add clearance for the back bottom middle of the new (bigger) alternator
I had washers handy so I went that route but so far it's working beautifully. I'll be adding on a 4ga power line direct from the battery this afternoon. I'll snap a pic then and post it.

Yes, I am running welding cable from it. I made new cables last year and had some left over. After looking at the pics you posted,I wish mine had the same kind of extension to put the cable on, would make it alot easier to do.

I think the prices are a little better from Quick Start Alternators.
6G Series Ford Power Stroke Diesel Type Small Case to Large Case Upgrade
This whole thread brings back memories from my escapade over the same thing this summer - https://www.ford-trucks.com/forums/9...lternator.html
I started out with the washer shim approach, but ended up stripping one of the alternator bolt positions in the bracket, replaced the bracket with a free donor from one of my customers, and took advantage of it being off the truck to do the grinding so that I could eliminate the extra tension on my serpentine belt.
I've been promising to snap some pics of the grinding which was necessary, and have kept forgetting, but I have the time and will do it right now...
As you can see, I took off more than was actually necessary, but it still wasn't too much... more was required for the back side than for the front.

I'd like to do the grinding, but I don't have a die grinder... yet. I didn't put on the 4ga power wire right away, but got some battery light flicker on the dash, so it went on the next morning. Several things I've noticed since installing the new alternator:
1. My mileage appears to have gone up.
2. My speedometer is more accurate now.
#2 is the really strange one. I've had my truck for over 4 years now, and was used to the error at an indicated 70 or 75mph. "75" was 71 before; now, it's 73. Nutty, huh?

Mine recently went out on mine, and I went with the DB 200a. So far no troubles, I've had the 4ga charging wire on for while. My old alt, you could see where the coils inside had been getting too hot and were starting to get burnt a little, this has been going on since just before RRE. But I'd say that alot of it has to do with the fact that I have 3 batteries and another massive D cell battery to charge as well lol.

2 year update
I'm not driving Nyx as much as I used to given fuel prices, etc. but this alternator has been holding up beautifully. I recenty (FINALLY!!) did an RR install so while I had the alternator off, I did the gringing to allow the case to clear the bracket. I'm satisfied with my purchase and would do so again, especially knowing that it's a small shop.
