I have had posts with 0 back links but excellent content assigned Page Rank 1-2 by Google with in 7-10 days.
But the posts are still linked from within the site, no? PageRank flows from internal links also, not just external. See this thread [webmasterworld.com] to get a bit more of a handle on PR basics.
