318 LA to 5.2 Magnum swap questions!

Hey guys. New here and I recently ended up with a 1973 D100 with a running but tired 318 and a 727 trans. I've done some trading and ended up with a 5.2L Magnum engine that will need rebuilding and it came with a new Mopar Air Gap Intake for it. Now this is my first Mopar never touched one befoe. I'm traditionally a Blue oval guy but my "chevy and mopar" buddies do the normal banter so I manned up and decided to try owning all three. Its the Dodge's turn. Now what I would like to know is what all will I need, to do this swap. And what parts can I use from the LA engine to make it work? Any help is much appreciated!
