A 347 is probably big enough to take advantage of the 205s if you build the top end (and bottom) strong enough to take some RPMs (5000+). Look at some of the builds in Fast Ford and Muscle Mustangs a few months back (late last year I think). They did a whole series on small block heads. Bottom line is the 205s are on the large side for a 347, but probably OK and if you ever wanted to go to a blower, you would have the perfect setup. Oh, and with the torque even with slow throttle response (which I'm not sure you will have), city driving will be enjoyable.
