Air Conditioning for an inline 250 or 292?

Is it possible? I've looked at the kits from Vintage Air and Old Air but haven't been able to find out if it's do-able. I've got the power steering and alternator on the driver's side of the engine and I'd like to leave them there. Also, I've got a GM HEI distributor that looks like it'd be in the way of the bracket I've seen (from a 250).

Anyone have pics or have installed AC on their trucks with an inline? Even pics of a factory install would be nice. I just want to see what I'm up against on this project so I can start planning.

Re: Air Conditioning for an inline 250 or 292?

I don't remember ever seeing one.I do kinow they were offered.I would guess the mounting brckets would have to be factory or made.I doubt there is much call for them thru the aftermarket.Most people build these trucks with a bellybutton(sorry sbc guys) or a BB.Only a few of us non-conforming die-hards want to keep a 6.
If it's a 250 there should be brackets on some cars,like Nova's(I've been told that's where to get power steering pump brackets anyway).For a 292 they may be the same but I have no knowledge on that.The interior parts you could get factory or from one of the vendors mentioned.

Re: Air Conditioning for an inline 250 or 292?

look in 70's cars and trucks in wrecking yards, AC came on L6, that would at least get the compressor mount.

Good luck

Re: Air Conditioning for an inline 250 or 292?

Yes it is possible even with HEI. Some early HEI units had a remote coil pak, the dist. cap was about as high as a point cap. I saw a 250 CI '75 1/2 ton in a local u-pull it about 2 years ago with AC. Could kick myself for not getting the set up off of it. As for a 292 a board member named GeeEmm posted a pick of brackets for it a while back. According to him there were 2 different set ups available, HEI and pre-HEI. I don't think he posts anymore though.
Nice pics of the 250 set up by the way.
I was told that 292 bracket was kinda rare but could be found in some Burbs, delivery vans and the like. If I ever see them on a 250 in the u-pull it again I'm going to grab the brackets and see if they'll go on a 292.

Re: Air Conditioning for an inline 250 or 292?

Panel, I don't have any plan in switching to a sbc, and air is a must if I'm to drive this more in the summer. 100 degree days with no end in sight. Maybe before next summer I'll get all the piece together?

Thanks, Rod - that's what I was looking for. And some specifics. Must not be an HEI because there's a coil there below the AC compressor. I wonder what type of compressor that is?

Re: Air Conditioning for an inline 250 or 292?

Chuck - the bracket appears to bolt to the head, and the head the same between the 250 and 292 - so maybe it would work...

Re: Air Conditioning for an inline 250 or 292?

I would think vintage air would have ac compressors for the L6 motors. I've seen eary F1 pu's with the clipper 6 and have vintage air

Re: Air Conditioning for an inline 250 or 292?

69 hafton,
Give Mike Buratovich, Vintage Air Sales Manager, a call on this one. He has all the brackets and everything needed for what you are wanting. I did this originally on mine. Only thing I had to do was get a harmonic balancer off a late 70's/early 80's GM car, like a Malibu if I remember correctly, to get the extra belt groove that I needed. I was able to get an older parts guy at the Chevy dealership to research this for me. I would offer up my old one, but I gave that complete engine to Krue. Here are some pics of the set up I had.

Re: Air Conditioning for an inline 250 or 292?

I am buying a 67 chevelle (it's a 4 door, but better than nothing!) and it has an AC unit with an L6, I'll try to get some picts, they are out there, they came from the factory with ac and L6's as well as someone in the aftermarket has to do it. Do a search for AC inline six and see what the net serves up.


Check it, one search netted hundreds of hits and this is the place, hope you like the service!!

Go to this link, it says they do the chevy and GMC 6 so you V6 ers can do it as well!!

Re: Air Conditioning for an inline 250 or 292?

I bought a Vintage Air unit and it came with the bracket for my L-6 250ci.
When you order over the phone they will ask you what type of engine you have and ask which side you want to mount the compressor.

Re: Air Conditioning for an inline 250 or 292?

Chuck, before you invest anything, I found some threads on inliners that says there are differences in the 250 & 292 head. Mainly the difference affects the power steering bracket that you use after swapping. Keep the ps bracket with the head it came with.

The passenger side of the heads may be the same, but I've heard that you can use a 250 head on a 292 and vice versa.

About AC on a 292, I got an email back from someone at GMC Pauls that said the brackets are specific to a 292, but they are available in the Old Air kit and will work with a HEI distributor in place. I'll check into the Vintage Air kit also, but from what I've seen, I like the Old Air kit.

Any other pics? It's nice to get all this info in one thread, saves hunting later for anyone interested. Subtle, was that a 250 you had? How many rows did you need on the harmonic balancer - I've got 2?

The 292 balancer is unique to that engine and is only found in trucks(from what I've been told). Will the pulleys from a 250 bolt on a 292? Good luck finding a 292 factory AC truck that hasn't been crushed.(I would think)

Re: Air Conditioning for an inline 250 or 292?

Thanks Hafton. I still think if I see a 250 set up I'll grab it, might be able to make an adapter plate from 1/4 inch steel to get it to line up correctly. My truck doesn't have power steering and I'll probably keep it that way for now.
In looking at the pics from 2 different sources I see that the routing for the drive belts looks different. In the first, the belt wraps aroung the water pump and crank, in the second it bypasses the water pump and drives both the AC and PS. I think the first set up would be more reliable and looks better.

Chuck
