Pick up a 318 or continue my search for a 360

I went with my 318 because it was cheap, low mileage and running. If you're going to invest in machine work, in my opinion, 360 all the way. The only exception IMO is if you're going to stroke it, then the two are close enough for me not to worry about it. If you know it's a good running engine, $350 is cheap.
