1974swinger-mopar newbie

hi everyone, new to the forum and to mopars. My girl found a 1974 dodge dart that she wants to redo. It is a swinger with no engine but fair body. She doesn't necessarily want a complete to factory original restore....i have heard alot of people discussing a magnum swap is this the way to go for daily driver or should i go old school? like i said i really don't know mopar yet so any suggestions for newbie will be greatly appreciated thanks
