360 magnum or LA?

Hey all, I'm putting together a 71 dart drag only car for my wife and I to toy with. Since this is a tight budget project(what isn't) Im gonna use what I have available. For engines I have a 70's 360 and a 96 360 magnum. I also have a 65 383 but it is completely dissasembled. The magnum ran great in my father in laws tow vehicle, just low oil pressure(worn mains) the 360 la runs ok but I don't know much about it. Looking to just get down the track so the wife can learn the ropes. I will build something more potent later. So my question is, which engine is more ideal for my current goals?
