I think …
Have a good squeal when I rev it up from say 1,000 to 2,000 rpm. Sometimes on start. Or when the a/t kickdown is used.
Mostly annoying. I took off that belt and the alternator belt - no squeal. Put the p/s belt on and got the squeal. The belt also runs the water pump. Could that make the squeal?
Anyway, the belt is in good shape but with the naked eye it doesn’t like it’s perfectly aligned with the crank and water pump pullies.
Any guidance here? Thx
Tighten the belt.
It’s pretty tight Bill.
How do I gain more leverage on the pump or bracket?
I use a pry bar and work in between the bolts on the front to get leverage. You can put a rag on the pry bar if you don’t want to scratch anything.
Ok.
Is there a way to insure the pulleys are aligned as straight as possible besides eyeballing it?
While its idling carefully spray some WD40 or similar onto the pulley and/or belt and the noise will instantly disapair .
Yeah, it’s not making noise idling, or running. Only hear it if the rpm goes over 1,000 during start, or if I get into aggressively while driving and it’s between 1,000 and 2,000 rpm.
Just annoying
70’s with the Windsor have a one motor & 1 (or 1/2) year setup. Very unique!
My 1st guess is the alignment is off due to missing washer/ spacer(s).
While belt is off, turn pump(s) by hand. water is free, and p.s. is bumpy & turns almost free.
Try a laser pointer in a flash light or a level to help see alignment issues…
Maybe some typos in there? 
Anyway, looks to be about 1/8 inch off. Gonna add two washers as spacers in the morning. Here’s a shot.
Looks like you have a foreign part there! Maybe that nuts is metric? or Chevy? lol
Look here for your spacer
Hah! Yeah, I’m sure that “nut” is non standard. Does anyone know the proper spacer size here?
WCCC has a power steering spacer for my car WITHOUT a/c. It is listed as 7/16 i.d. by 3/4 inch. My car came with a/c, but it has been removed. My “spacer” nut and washers are about 1/8 inch shy of 3/4 inch, so by eyeball it appears this spacer would work.
I can’t see why an a/c compressor would affect proper spacing? Side note -this original used spacer is about $30. A repro is $6.
IIRC, the A/C bracket(s) use a common bolt, mounting point etc.
That’s why the spacer was used to "make up the thickness of A/C bracket(s) in non A/C Cats.
Most of the 70 carryover Windsors were put in w/ a 2V carb and 4 speed trans.
The 70 Windsor for example had a few major changes.
1st. The radiators are now crossflow, the water pump was clocked to 5 o’clock from 7o’clock. (looking at motor)
2nd. the power steering pump bracket is now stamped steel. Both 351 motor used the same pump bracket. No longer was the aluminum C9 part used.
3rd. The pulleys are different. Can’t recall exactly, but I believe it was crank & H2o. The PS pump pulley was now dome shaped.
Best of my recollection, I think 
That makes sense. The a/c bracket was probably 3/4 inch thick at that bolt.
Annoying squeak is gone.
I added two washers to get the 3/4 inch spacer previously provided by the a/c compressor bracket. I used a wonderbar/superbar to gain leverage between the bolt and the bracket. I did it myself, but it would be better with two people - one levering the wonderbar and one tightening the bolt.
Thx for all the ideas.
