just did a 3g upgrade

Did the 1G fords come with a 10mm belt or a 13mm for the alt/pulley?
What's what I really want to know.
I've got a 10mm belt on mine right now and she squeals like a stuck pig. Wondering if the last owner put on the wrong sized belt cause it sure looks like a 13mm would fit without protruding up above the pulley.

I ended up switching to a CVF Racing serpentine setup which solved the issue. Not a cheap option, but it got the job done nicely.

I'm running a single belt on mine. I've had no squealing at all. I had previously removed all my pulleys and bead blasted them and repainted them. A new pulley was installed on the alternator. Its no tighter then it should be. I am not running an amp or any high amp draw electronics on it however.

Link or P/N?
I'm not ready to spend $$$ on the CVF pulleys just yet, but don't get me wrong... if I had the extra money, I definitely would.

Are you running a notched belt or a solid belt? What size of belt (width)?

I bought the full kit :

I already had the AC and PS brackets so I was able to get a discount on the system.

Reviving to discuss pulleys, and b/c I know you all are missing this thread; I mean it's been like two whole months. Anyway, I picked up two 3g alternators at the picknpull last week. Both tested good at local parts store. The one going on came out of a 93 Taurus wagon and the backup out of a 96 stang. Old serpentine pulleys came off no problem with 18v impact. I figured I would go ahead and get a new v-belt pulley to go on the 3g. Will this Powermaster 111 work?
https://www.summitracing.com/parts/pwm-111/
I measured the shaft diameter of the 3g and it is right at .671", same as the pulley bore diameter. The difference is this pulley has a slightly smaller O.D. (smaller by only approx. 0.350") meaning the alt will spin faster right? Charging more at idle?? I don't necessarily need this, but will it hurt anything?
I have seen all the posts about going to a 2 groove pulley, but I would rather not get into changing other pulleys to complete the setup.
I have read the 3g wiring info extensively so hopefully I have that figured when I go to install this weekend. Pretty straight forward; looping the yellow from alt plug back to charge post on alt, going to tap into red/green just before it enters the old voltage regulator, wht/blk stator loops back to alt, and charge cable to plus side of solenoid (thru 175 amp mega fuse). Any reason charge cable can't go directly to battery? I think the Painless Performance kit instructions show going straight to battery. Also going to run the yellow/blk from harness to + side of solenoid.
I will eventually go to rocketman for a custom voltmeter to replace my stock ammeter (truck has no idiot light, just stock ammeter).
Heres to hoping im drinking beer after no more than an hour this weekend.

Just wanted to contribute my $.02 to this thread and say I performed this conversion on my 65 F250 (352 FE motor) this weekend and it was as easy as advertised. 130amps charging at a dead steady 14.5 volts no matter the load. $30 from my local Pick n Pull out of a 96 Taurus (Didn't hurt that the alternator was in near new condition)

Went ahead and ordered the powermaster 111 pulley. The smaller O.D. shouldnt matter since i have plenty of room in the bracket for adjustment to tighten the belt to spec and the alternator rpm will not even get close to what the 3g can handle. This truck is a cruiser and i will probably never push engine rpm above 4000. Cant wait to get this upgrade done and see the difference.
