So, with driving the car all through last summer w/o air, I figured a good winter project would be to add in an aftermarket a/c kit. Got all excited and ordered a mark IV under dash unit and a complete a/c install kit with an A-6 compressor. I then placed out a post looking for all of the brackets. A couple of people on here think they may have all of the brackets so so far so good but now I am confused when I look under the hood at my 330.

From my understanding, the compressor mounts where the alternator is currently and the alternator is then moved to the drivers side of the motor. So what happens to the power steering pump? Does the driver side alternator bracket mount to the p/s bracket in some sort of way?

 

Ask for some one to post a picture of their stock AC setup on a 350 Olds or go to the junkyard and pull the whole setup off a 350 Olds with ac including all of the pulleys. May even have to change the water pump due to the length of the shaft to use a three grove drive pulley. I'll let others chime in. You will also have to custom modify the AC bracket to use the after market compressor as it is different then the stock compressor. Sounds like a lot but just take your time and it will not be that hard

 

I am hoping for some possible pictures or a good understanding of how it all fits together. According to the vendor of the kit, the compressor should bolt right up to the bracket, but the kit also includes flanges and other things to make the compressor bolt right up if it is not correct.
I would go to a junkyard to grab the parts but no one around here has anything that old anymore, at least the 6 that are by me don't, they all deal in late model stuff.

 

The 330 block shares the same architecture as the 350 engine. I used the 330 alternator bracket on my 455 in order to install it on the passenger side of my 57 Olds when I installed the engine. It fit fine with no modes at all, and the rest of my brackets for the power steering came off of a 74 350 Olds.

So anything in Olds that has a 350 in it should work fine all the way up into the late seventies

 

This is just my opinion, but with the technology advances, there is no reason to use a big, heavy A-6 compressor. I bought an aftermaket kit using a Sanden. Tiny. Small evap and condenser, too. Blows ice cold (black car in Florida).

 

That's the way I am going with my 48 Olds, but you still need a bracket of some kind correct? What did you use for a mounting bracket?

 

Power steering pump stays in the same spot.

 

The company I bought the kit from had both the sanden and the A-6 style. The stipulation with the sanden was that it would come with a "blank" generic bracket and it would be up to me to bend and drill the holes into the bracket to make it work. Going with the A-6 gives more of that original look and allows me to use the factory brackets of which I want being as though I also went with Mark IV evap unit.

The AC bracketry looks the same as my '71 350 , the alternator and power steering pump mounting is totally different.

 

72 is totally different. Ron sent me some pictures of his with the A/C and
I am no longer confused . Looks like the alt bracket mounts directly to the p/s bracket and the alternator sits in between the p/s pump and the temp housing. Can't wait to get this done so I can add it to the build section along with all my photos and maybe give some other people ideas on how to get one of these aftermarket units installed.

 

I found the brackets. PM sent

 

Bryan did those pictures work for you?
If you need more let me know.

I took the following pics of a '67 Cutlass engine with a factory A/C setup before I removed all the pulleys and A/C related parts.
(Should be identical to your '66.)
I plan to re-install the A/C conversion on another car.
I also have the complete A/C cowl section intact if you want detail pics of that.
I know you said you plan to use an aftermarket set-up, but, I thought these might be helpful,
especially if you were to do an original conversion.

 

Ron - yes those pictures were great.

67442nut - Thanks for the post. I think I have everything I need now.

Thanks everyone!
