You will see varying opinions on what the PR should be on the recieving end.
The pagerank give-through will depend on if the page is a high or low PR7 page.
PR4 or 5 could be possible.
Check some of the 400 links and see what PR the lowest Pageranked page gives.
(the original page must be in its backlinks though)
However, remember that the total PR a page has to give gets divided-up among all the outbound links. So you're not going to see any great benefit in being on a page with hundreds of outbound links, even if it is a PR7.
You would likely get more PageRank credit from being on a PR 5 page with only a few outbound links than a PR7 with 400!
