Superfreak,
I just picked up a Hemi block with the same part number as the one in your pics yesterday. It has never been built, and was curious about it. So I guess it is a World block. Any idea when these were produced? Do you have spec sheet on it?
The pad near the fuel pump is stamped:
0811060A445
P5153861

No idea when these were produced. Bought mine from Dave Dudeck and it was new untouched but how long he had it for, I am not sure.
P5153862 is on the fuel pump pad and on the side of the block it P5153843 so not sure what is up with that.
