The biggest one I can think of from Audible is War & Peace which is 65 hours 24 min. and is 938 megs in format 4.
If the book is on MP3 CD though I've seen a fair number of 16+ hour books take up more than a gig due to the producers using a high sample rate (which is really unnecessary for spoken word).
