BB K member rookie

From what I read here at FABO it looks to be a 68-69 correct? ...and it takes a special block with extra threaded bosses on the driver side front?
I know pretty much of nothing when it comes to factory BB A bodies. I got a K member in a package deal with some other stuff. Its been chopped for an oil pan and poorly repaired. It came from a drag car, but I don't think it was an original BB car. Does this thing look like a real factory K?
