I kinda doubt the RV industry had the resources to stockpile 2-3 years of production chassis. As far as I know, they used a complete Dodge chassis, and none built their own frames/suspensions... but I could be wrong.I'm wondering if the RV people didn't stockpile some of the last '78-production 440s for their future use? Just as Dodge kept building their full-size vans one year after they said they'd stop production, so the van converters would have a popular product to sell, as they changed over to Ford or GM vans.
Perhaps those engines came from Chrysler Industrial rather than the normal carline engine plant? I believe that 413s were still available that way, even after all of the cars were 440s?

I also have a hard time understanding why they would continue production of the castings, without changing the date. It's more believable to me that they cast a lot of additional blocks, and then machined them as production needed them. IDK exactly what the storage would have been like, but it was a time before they had their parts storage killed off by Iaccoca.Nearing the due date of Chrysler ending production of any vehicles with 440's, advance orders from commercial 440 customers poured in. Chrysler fulfilled back orders for the 440 well past the vehicle production end date, all with 1978 date codes.
Winnebago, the best customer because of the huge amount of Dodge chassis/engine units they bought received these units until 1980, I think, with 1978 engines showing a 1978 casting date. That tells me blocks with 78 markings were cast for two more years.
I beat @saforwardlook has an idea about how/why this happened.
