I do not think so as the large six pack air cleaners would foul on the air con pump. I think.
Correct. The AC compressor would have interefered with the air cleaner on any multi-carb car, or on any car with a shaker. So no AC on any Hemi, 440-6, or 340-6.
Honestly, they could have worked around that pretty easily. I've seen cars with the big air cleaner reworked for the compressor. Chrysler just didn't want people with high output cars grenading AC compressors under warranty, in my opinion.
