No... I just hate the term "crunchy" used in this manner.
But, if you are asking for what is the typical mix of "rules" goodies and "story" goodies an average gamer wants in a sourcebook, then take a look at the SW:RPG Alien Anthology and Starship of the Galaxy. In my opinion, at least, they had precisely the right mix of goodies I was looking for.
There were stats for creatures/aliens/starships, and the stats blocks were compact and informative. this allowed them fit a lot of info into a small page count. For each entry there was a brief background entry. Enough to give you a feel for the creature or ship, but not so much as to take up valuable space on the page or make them completely useless when being inserted into a home-brew campaign. Both books included new prestige classes and feats, and alternate ways to use skills. Both had basic rules for creating new creatures/starship for scratch or templates/rules for modifying the ones listed in the book (these alone made the two books worth buying). The background entries were interesting to read and the art was pleasing to look at (especially in the Alien Anthology).
Many books even include a short adventure module.
