Good engine swap options

Hmm I didn't even consider a magnum swap, but wouldn't there be issues with the swap because of the computer? And they aren't carburated so that may cause problems. And I have considered a turnkey engine, would be easy, my only thing is I already have so many parts, I would hate to not use them. And I can do everything but machining simply because I don't have the right machinery. Put a 440 stroker together a few months ago, so it's not my first engine build.
