Here's what I know so far. I'm sure it had the 322 originally. The truck had a 409 in it and that is why it was purchased and the engine pulled. It was originally a hydramatic, at least it has the emblem on the doors. Guy was going to part it out but I am going to get the truck minus engine and trans probably for décor and so it doesn't get scrapped. I'd been looking for a good yard art truck and I think this will fit in well especially here in the Pacific Northwest
