none.
I could say that the 700c fork blades will be about 4mm shorter - but that will depend on how much clearance the fork is built to have, so it's not a definite thing I can generalize about.
As for trail, forks can be built with different amounts of rake (affecting trail) - it has
nothing to do with wheel size. A fork for a 27" wheel can have just as much or little rake as a fork built for a 700c wheel.
