No, that's a fine connection. My guess is you'll make that without running, even with a factored-in 20 minutes late on the inbound.

Don't fool around at customs though, because you have to run the gauntlet once more in security to get in to the domestic terminal. (Although somebody posted something here a month ago saying there might be a "bus" from the International terminal direct to a gate in the north terminal--- if there is such, take it).
