Google used to index only the first 101 KB of any web document (that's why you may have often seen 101k as a document's size on Google SERPs). It seems that it's no longer the case: a search for gives as first result the page http://www.gofigger.org/hphist/gutenberg/7ethc10.htm which is 513k.

We reported previously that but at this time we couldn't find any example.
