89gtsleeper

I pulled the intake off my car this weekend, and on the top of the block, between the heads, it says XXX in two different locations. I have a receipt that came with the car signifying that it was a sportsman M-6010-B50 block.... My boss told me that they put XXX on the stock blocks though... Did I get ripped off, or is this actually a sportsman aftermarket block??? I can't seem to find any information on this anywhere... I found a few pictures of the block, and it looks the same to me, but I'm sure they all look very similar in that sense. Thanks.

btw, this is from an 89 gt with a 302...
