Is that an iron block like it looks?

Also, I can't find the casting number 12551384 you posted for any LS block, nearest I found was 12551364, which is a 6.0L cast iron LQ4 truck block. The LS2 is aluminum of course and also had the knock sensors mounted to the side of the block, not in the valley like in that pic. Really not looking like an LS2 to me..
