I've seen a few 440 swaps online just by looking around. But I have a friend with a old 400 big block out of a Challenger that he was going to stroke to a 451. He said I could buy it from him and he would put it in my truck haha.
No replacement for displacement. Used Viper or a SRT-10 motor and all its goodies needed to make it run, should be a ez'r swap as these trucks came with a v10.
