'74 Dart V8 swap

Just bought a 1974 dart with a slant 6. Would like to convert it to either a 318 or 360 since 340s are scarcer than hens teeth and twice as expensive. I'm new to the form and am looking for a list of everything that needs to be changed to do the swap. I don't know if such a list exists, but if it does I sure would appreciate it if someone would point me in the right direction. If not any and all help would be more than welcome.
