Found a 351C block with casting number D2AE bored already .30 over. Have several questions about block:

Block needs to be bored again due to scratching on piston walls, most likely .30 over again.

Can 351C be bored .60 over total and still be ok?

Attached pics and wondering what your opinions would be on block??

Thanks.

.040 is it without getting it's thickness checked.
