Shows to be a 76 or 77 model used in several different body styles behind a 318. Doesn't tell if it's a 904 or 727 though but since it was behind a 318 my guess is it's a 904.
If you ever want to look them up here's a link to a page with the part #'s.
At the top of the page there is a picture of the oil pans used on Torqueflites. The one on the left is for a 904 and the one on the right is for a 727.
