Now to my question, is this a picture of an LT5's lower block portion?(ASSuming a 1990-92-by its 2 bolt per main)

Yes I believe you're correct with your assumption. The image looks like it may have been from a post by JP back in '07 here's that post:

Paul - your image is with it installed and Hog's is the internal aspect of the crank-case half facing up.
