Your bottom bracket height will also end up 4mm closer to the ground, possibly more if you are using a narrower tire. (many 27x1 1/4 wheel bikes end up converting to 700x28 or 25c tires, with less sidewall height)

I hate to contradict you Martin, but I think the difference in diameter
is more then that. If you try installing 700c wheels on a bike set up for
the brake pads will be bearing almost entirely on the sidewall of the tire.
think that you need to be able to lower the pads about 10 mm.
