I am working on a recipe that right now has 8 oz of molasses incorporated. Should I expect higher attenuation like I would if adding a simple sugar or is molasses less fermentable?

Blackstrap molasses is less fermentable than sugar because of its mineral content.  I'm not sure what molasses you are using.  I would assume that the lighter grades of molasses are nearly as fermentable as sugar.  My 2 cents.

Definitely not blackstrap. I believe it is "light" unsulfured molasses.

My main concern is having a dark beer that finishes too low. I can try to offset it with a higher mash temp. There is no crystal malt in this beer.
