Please excuse my extreme lack of knowledge with respect to 1966's, but did '66 Shelby's come with an A/C option?
I know 67's sure did, but were they the first model year available with factory A/C or was it in 1966?

The only 66 GT 350 that I have ever saw with as built AC is the red convertible.

To my knowledge, A/C could be dealer-installed but not from S-A.

Yes . SA had to get a special variance from Ford to allow the A/C on a hipo most likely so that the warranty would not be voided. 66 GT350 Converts only. A/C not available on regular production 66 GT350's from Ford or SA. The converts were special.

None of the K code Mustangs (Shelbys included) in 65/66 had factory AC, PS or PB.  The exception has already been noted.

Bob, I have an aluminum a/c crank pulley  that was "supposedly" part of a batch of special pulleys made for those '66 convertibles to be used instead of the Ford cast iron pulley.

Is this a possible legitimate part, or just a pipe dream ?

I suppose it could be but I am not aware that any of the converts used other then the stock Mustang pulley. I cant think of why they would need to. I will check with a friend who has worked on 3 of the 4 converts.

the reason for the aluminum pulley that I was given when I acquired it was that the HiPo engine had too much weight on the end of the crank with the cast iron pulley, i.e. not rpm friendly.

This aluminum a/c pulley was  a very good fit into the crank pulley on my '65 HiPo. I'll post a photo of it.

I acquired this pulley a few years from a reputable west coast HiPo parts specialist. I've  been dealing with the seller for many years. I know he believes the pulley was as described, but is he right ?

the pulley was check for Pookie DNA, fingerprints, and radiation waste signature. Negative on all counts.

I'm not making any assertion for what it's history may be, thats why I'm asking Bob if he's come across one like it .

I do know it does fit the HiPo crank pulley very well, and the HiPo engine vibrates less, much less, with this pulley in place vs. the stock Ford cast iron pulley.

I talked to my friend John Brown who has worked on three of the four converts and he confirms that the pulley is the same as whats on the green car and the blue car. He is not sure of what the red car has currently. Apparently the cast iron pulley will not fit on a hipo balancer well because of the way it is made. It does not sit flush .Maybe more about a lower production pulley made up for a special application then a high RPM issue . The aluminum certainly wouldn't hurt however.  The later continuation 66 convert I had used a hipo replacement pulley and the cast iron Mustang pulley fit fine. John reminded me that SA needed a waiver from Ford because the hipo didn't meet minimum cooling standards at idle. The converts were the only 4 hipos that came with A/C that ether he or I are aware of. There is still a question on who installed the A/C on the converts,Ford or SA not that it makes much difference ether way just interesting.

Z      I know that the later 67-68 steel AC pulley will not fit the C5OE hipo damper.  If it fits, it is so snug that the outer dampening ring is not free to move as it should.

For 67's with AC, the outer ring of a C5OE damper was machined down on the inside so the steel pulley would fit.
see the discussion here:    http://saacforum.com/index.php?topic=21196.0    Pictured is a C5 damper modified by Ford and restamped.  Later cars got the C8ZE-A damper with the wider pulley mounting area.
 
A test would be to measure the diameter of your aluminum pulley at the bolts end and compare to later steel one.

I remember seeing the Red 66 vert at SAAC 17 just restored by Drew Alcazar. Noted that it had the later steel pulley mounted to a C5 damper - looked like an interference fit.    Asked him and he said that was how it came?

thanks for the verification Bob.  

Yes, I did run into issues getting the stock cast iron pulley to clear the HiPo balancer cleanly. This aluminum pulley was a much superior fit.
