This one has the right set up on it

That set up runs as smooth as butter. With or without the clutch fan it does not seem to make a difference.

I know of a young fellow that was killed by a fan blade that came off. In the picture that you have shown here it would create two different speeds on the belts and the reason is because you have two different size groove diameters on your water pump pulley. The size of the alternator pulley and the size of the power steering pump pulley has no variation of speed in the two belts as long as the two groove diameters in the crank pulley and the two groove diameters in the water pump pulley have the same diameter. The water pump pulley you have shown has two different size diameters on it. This type of pulley would not use a belt that also went over the crank it would only use one of the two belts over the crank shaft and not both of them. A pulley such as you have shown could be used to drive another accessory but the belt that drives the second accessory could only be put around the water pump and not over the crank or they would fight each other and squeal and one of the two belts would wear out real quick.

I have drawn a picture that shows how it works with two belts over the crank and water pump. In this picture the two grooves of the pulley on the water pump are of the same diameter and the two grooves of the crank pulley are of the same diameter. The fact that the power steering pump has a different size pulley then the one that is on the alternator has no effect on belt speed.
it wouldnt run 2 speeds because it wouldnt go 2 the water and crank so you may wana read all of the post before you say its not correct and by the way stock 2 belts dont even go to crank and water pump

experts

So now another expert that doesn't have a clue. If you look at the picture that you say is correct do you and others see that it has belts on it that don't fit the pulleys. Look at the edges of the belts. Also you are telling the op all the pulleys need to be the same on the water pump so you can now explain how this pulley is correct when it has smaller pulley on front. Come on guys the op has a small belt or alignment problem and now you are wanting him to change everything.

I didn't say all the pulleys on the water pump have to be the same size I said if you run two belts from the crank to the water pump then the two pulleys that are being used and that are on the water pump need to be of the same diameter. Also the two grooves of the pulley that are on the crank and are being used for the purpose of the belts that go up to the water pump need to be of the same diameter. The crank pulley and the water pump pulleys do not need to be of the same size diameter and they are usually a little different in size.

In the case of the pulley set up in the picture I posted (the picture that V8&4spd originaly posted) it is correct. He is using a factory pulley that has a smaller pulley on the front of it for another accessory. But you would not put a belt on that pulley and run it down to a pulley on the crank shaft. Because then you would have this belt running at a different speed.

Chris is correct about different water pumps, pulleys and what happens when they are not right. I probably have all the different pulleys and water pumps. Some people on here are just stirring the pot. They talk the talk but don't walk the walk. You can change a $15.00 or less pulley or you can spend the same amount on a new fan belt.

You will get it sorted out. It's a Chevy parts fall out of the air. You can buy brand new crank and water pump pulley for $25. The belts run about $15 a pop now.
