As long as you have at least 13 - 14 inches of vacuum you should be good to go. Most stock type engines run around 20 so you should be okay.

Camshaft specifications usually determine your vacuum levels at idle, not displacement. As stated above, anything over 14" Hg is typically adequate, 17-20" Hg is opt, 12-14" Hg is marginal, and anything less is a better candidate for manual brakes or hydroboost.
