yeah it is, I read it wrong.
5th bullet under 1997 -'04 - 5.7L Cars:
The 1256118 casting was originally designed for the high performance LS6 that was introduced in '01, but it showed up in some LS1 applications in '01 and '02 and it was used for all the Corvette motors in '03 and '04. The only difference between it and the previous block was the addition of two cast slots in each of the three center mains. They replaced the holes that were drilled through the bulkheads on all the other '97-'01 blocks.

well, the block IS an LS6 block as mine is. It just doesn't mean anything but I still found it interesting to know that I had one. Guess it's just another car nerd thing to know
