440 in my 70 swinger???

First time doing a car watched dad do it before gonna get his help with alot but id like to get some input from other people. was thinkin 383 but i was told weight to power 440 would be better. Currently building a front end with a small block k-frame what is in everyones opinion good bad better etc. also throwing in bigger sway bars and such obviously. any kind of extra parts would help too :D
