1974 Dart swinger 318 to 360 swap

Hi everyone my name is Andrew. Glad to be a new member :finga:. Im new to mopars so i need some help and tips. I bought myself a 74 Dart swinger with a 318. I found out the 318 has a blown headgasket or something. Water in the oil. Anyways i dont really want to mess with the 318. I can get a running 360 with transmission for cheap from a guy i know. $400 Its out of a 75 motorhome. I was wondering what exactly what i need to swap in that 360. Im gonna beef it up a lil first before i install it. Any help, tips, suggestions appreciated :cheers:
