I saw a 1968 Charger that the owner had installed a 426 Street Hemi motor in and he had installed a stock Mopar V twin air conditioning compressor on it up high on the passenger side like Mopar installed them on the 440 motor back in the mid 1970s before the first gas crisis.
I think he worked in the Dodge Dealership In San Bernardino, CA as a mechanic so he may have had access to some Mopar parts you and I couldn't get back then to do that install with He said the air worked really good, it does get above 100 F frequently in the summer down there.
I've never seen or heard of any other stock Street Hemi productions cars having air conditioning stock from the factories.
