Where did you find those numbers on the block- they don't look familiar at all.

The most valuable numbers would be on the stamp pad in front of the R/H cylinder head.

Those look like the numbers behind the timing chain. They match mine exactly (I think you meant that to be a g12). Now if it came out of a corvette, who knows. GM dropped those 010 blocks in a bunch of models.

Is the VIN pad stamped?

In case you're unsure of where you should be looking, Year One gives you a good picture: http://www.yearone.com/yodnn/tech/Ve...2/Default.aspx
