I'm getting serious about buying one in CA and I know CA has/had stricter emissions than the rest of the states but I can't find out for the life of me whether or not an air pump was ever on one of these things.
I read some articles that stated that Mopar was able to use some loopholes in 78/79 to skirt the "performance" 360 through for the LREs because of their weight but they don't say anything exact and they certainly don't mention anything special about CA.
I called a couple smog shops asking if they had a book that could tell me what exactly I needed to be connected emissions wise to pass inspection and they either wouldn't tell me or they said they just go off of whatever is on the emissions sticker. I found an emissions sticker for I believe a 79 Ramcharger on ebay and it mentions catalyst, EGR, PCV and cannister but no mention of an air pump.
