Pulley setup

[my5thmopar]

Anyone suggest a lower cost setup other than CVF/March. I want to add AC to my stock 440 but, I think I have a miss match of pulleys. Do they make an adapter bracket for the 2 groove Sanden? Really, I’m trying to figure out to get the correct pulley setup.

Vintage Air has pulleys and brackets.

You can try these guys too:

When I removed my A/C set up from my BB I got both pulleys at 440 source.
They were the cheapest around at 49 bucks each. Worked out great for me.
They also have the pulleys needed for when you wanna add A/C

Hoffman's makes some beautiful repro items if you're looking to go for the stock look, which I believe you're not. Anyway, it's good stuff.

FWIW, there are at least 5 different pulley setups for BB, depending on whether AC or not, and what year. Mixing/matching complicates things and makes for frustration.

That is probably what happened. This is a 76/77 truck engine. A well known Mopar guy at the last show, took one look and said: That's not right. I really don't care what setup to use but, I sure don't want to spend $1200+ The only way I can see getting the correct setup is to replace all of the pullies.

Yes. And depending on which set of pulleys you choose, you may also need to switch to a different water pump housing / front cover.

 

[fury fan]

Agreed, and depending on that water housing, the radiator lower hose location must then match.

My5thmopar -
It might be best to get the AC compressor and the brackets, and mount it, then see what pulleys you have and how they align.
Then you can find out what pulleys you need to find.
Compare them to online pictures of loose/complete engines and start to familiarize.

Fortunately for you, I have an assortment of pulleys, and most came from AC cars, I could sell you some at reasonable cost?
Unfortunately, I cannot tell you what ones would work for you, but we can work thru that?

 

[my5thmopar]

This is what I have to work with. Anyway to tell what I’ll need to add AC. I’m going to use a modern Sanden compressor. Will I be better off tossing it and starting with a complete setup? Craig

Anyone?

Here's what I think you need...

The lower pulley needs to be from an A/C car.

Pulley on the water pump needs to be BPE Water Pump Pulley - Bouchillon Performance Engineering
You will only use one groove on that and it will drive the power steering too.

The alternator bracket needs to be from an A/C car too. That would move the alternator forward. Belts would wrap around lower pulley, over A/C pump and over the alternator pulleys.

I may have the lower pulley, but the offset hole may or may not fit. Simple fix is to hit it with a rat tail file and oblong the offset hole.

I also should have the alternator bracket from a '70 A/C car.

This is mine. '70 300

This would give you the same belt setup as a '70, but without needing the idler pulley.

If you are interested, let me know and I'll look at the stuff and give you a fair price.

 

[Big_John]

Scratch the Boucillion pulley. I think the water pump pulley you have will work.

 

[my5thmopar]

OK I see the alternator is the tension for the AC and PS has its own. How much clearance above the water pump and the belt? Ya know I have several pulleys from various engines so, maybe I can come up with something. Thanks for the idea.

You'll still have to move the alternator forward to get the double pulley to align. The bracket takes care of that.

 

[my5thmopar]

How much clearance between belt and pump?

I'll grab a picture in a bit.

Does this help? Power steering pump is off right now.

Yes, thanks. Craig
