340 r.i.p.

I am leaning towards a magnum roller cam motor. I found a 97 magnum 318 with high mileage 177k for $200. When everyone recommends a magnum are they talking one to rebuild or one with lower miles and put in with some performance mods. Are magnum motor any more or less to rebuild than a LA motor? If i do go magnum it would be carburated and look like an LA, I just always wanted a classic muscle car look under the hood, no computer, injectors, lots of wires.
