No everything will be turning at the right speed, just a question of belt traction. Unlike underdrive pulleys which cause charging and cooling issues.

Ok. For some reason I thought pulling the pump to 1 side would damage it. I tried looking up a.c. delete pulleys as well, couldn't find a v belt style for olds. Would be nice to have a serpentine belt style but seems like there's alot involved with that trying to make it work.

He has to or get different pulleys.

Then get the right pulleys. Or hook up a functional A/C unit.

Using an unused accessory, like a smog pump or a/c compressor, only as an idler pulley just ain’t right.

If you can afford serpentine you can afford the right pulleys. Quit making it difficult.

I have know idea why GM did this in the first place. It didn't happen till the G bodies. The Vin 9 cars have the triple bottom pulley.

Want it to be budget friendly.....
If what I have works, then I will use it. Don't need to spend 500 on a serpentine system. That's why I was gonna throw the a.c. back on. Because I'm ok with that if the squeal goes away.

Well, kinda. Maybe. 83 and early 84 had double bottom pulley (triple if you count the A.I.R. belt) and triple water pump pulley (with the front one a tad different size for the alternator). The alternator came off the water pump pulley only. In actuality, G47 VIN Y had this system pretty much 82-88 IIRC. See top right picture (LV2 w/C60) below. Since all VIN 9 required C60.

Sometime in January 1984, the H/O got a "new" system which carried on with VIN 9 cars the rest of the way through 87. It had all the water pump pulley sheaves the same size. Now, the alternator belt wrapped around the crank pulley too as well as partially the PS pump. The PS pump got a new 2 groove pulley. So the bottom pulley got 3 grooves (4 if you count the A.I.R. pump pulley extension).
