Is this tag fake?

[Flatdad]

The tag indicates it was a four speed AND air conditioning. I didn't think those two were allowed together. Have I got my facts wrong? Is this tag fake? or is this a unique combo that slipped through?

[JS29]

Yes! @usraptor  bought a new 1970 383 4-speed 'cuda with air conditioning. If you look for cars you wish you never sold, in general  topics he has a story about it.   

[B5fourspeed]

You could not get a 4 speed with air on a 440,440-6,or Hemi.

[RUNCHARGER]

Correct, 340 or 383 with A/C no problem.

[1 Wild R/T]

Correct, 340 or 383 with A/C no problem.

And even a 3:55 gear was available...  No 3:91...

[JS29]

No ac with a shaker hood or any three two barrel carb vehicle. 

[7E-Bodies]

Looks legit. I agree with @B5fourspeed 

[anlauto]

I owned a 71 Cuda with 340 4spd with AC

[redgum78]

So no AC on a 440 Magnum if you had a 4 speed? What was the reason for this?

[Flatdad]

Well I learned something today then! This pricing list for 71 challengers is what threw me off, you can see for option H51 (AC) it says NA with manual transmission.

I agree it wasn't an option on 6 pak, but Chrysler must have fiddled around with the idea......car#065 on battery
I have literature showing A/C installed on an 440-6 E-body.
Here's a few pictures from the text.

1970, it's ok to have H51 and D21:

[6bblgt]

AFAIK:
A/C was never available with: 3.54 DANA 60, 3.91 (8-3/4), 4.10 DANA 60
A/C was never available with multiple carburetors 1965-1972

1970 (ALL year)
A/C was available with 340-4 w/3 or 4-speed
A/C was available with 383-4 w/3 or 4-speed

1971 (EARLY)
A/C was available with 340-4 w/3 or 4-speed
A/C was available with 383-4 w/3 or 4-speed
* during the 1971 model year A/C was discontinued from the above 2 combinations

@Flatdad what is the date on that version of the price guide?

it also shows E24 225 slant 6 with a 4 speed .... as far as I know, a 4spd was never an option with the slant 6

That was my understanding. As far as I can remember, the only American car that offered a 4-speed with a 6 cylinder was the Mustang. And that was only in the first year of production.
