I need another belt going to the power steering pump, which is why I need a double grooved water pump pully. Atleast that's how I think power steering is supposed to work. 


You would think there would be one a double groove on the alternator?

Edit 1: I'm looking at the power steering pump I have, there seems to be a double groove attached to the alternator that came with it.

Edit 2: I phoned my father and he says the double groove on the alternator is for air conditioner.

To me it wouldn't seem stable if it was all one belt...

On my 1970's, the water pump pulley is the same on the 350 & 454.  Same with the power steering pump pulley.   Why do you need a 2 groove water pump pulley?  

I'll see if I can find you a GM parts book picture. Back in a bit.

Oh, and I am thinking the bolt pattern on that pulley may be wrong because it's from later years where the bolt circle increased in size.

I can't speak directly to an inline 6, but on my V8's the power steering pump is turned by a double grooved crank pulley.  One belt goes around the crank, water pump and alternator, and another belt goes around the crank and power steering.  Sounds like a little research is in order.

Ok good news! I have all the right brackets and found the holes in the engine. Though for demonstrating purposes im using the alternator which I do not know works.



The double notched water pump pulley i currently have would not work in any way as it doesn't align up with anything, even if I did modify it to fit. So im probably going to have to order something online.

Now the question is determining how the belts will be set up. I feel like im going to need 3 belts in total. One belt for the crank and water pump pulley (assuming im getting a double notched one). One for water pump pulley to to alternator. And finally one for alternator and power steering pump. Which all align up with corresponding pulley notches.

What do you guys think?

if the water pump onr dosent line up you can tap the hub in or pull it out to make it work

I have all the stuff he needs.

Timbuk,   those pics are for a 70's style setup, it may just confuse the issue,

There should only be 2 belts,  so far, blake has all the right stuff,  except for a waterpump and wp pulley.

I have a 66 Beaumont here that's a parts car...  couldn't remember if it had power steering....

here's pics for reference... 

another member here spoke up that he has the required parts, so I'm not trying to jump a sale here..reference only..
