Fridays are pretty busy days, so if you're arriving flight coincides with a few other international ones, (i.e. after 3 PM when most European flights start coming in) you will be cutting it pretty short - the lines at immigration are notoriously long, but you also have to pick up your luggage,clear the customs and then drop it off for your connecting flight (fortunately, you don't have to take your luggage to check-in counters or anything, the drop off area is right past the customs check). I've done this whole ordeal a few times in less than two hours, but it will feel a bit crazy.
