I have one out of a normally aspirated car which has already been drilled and tapped for the turbo oil return. As you probably know that is the only difference between turbo and N/A. Looking to get $250. firm. Located in Elizabethtown, KY. Hopefully you are close by since I've seen you posting on 502underground also.

Randy is right, the only diff is the turbo drain hole, there are no other differences between 109 block castings turbo or n/a. well, maybe a few have a clutch pivot hole/dimple due to being a replacement block, seen a few of those.
