360 On crack

Dan the man said
Not the distance. I'm sure that it's not a crack

That’s a crack Dan. Want to know how I know it’s a crack and I’m not guessing?

Because there is no parting line there where the multiple pieces of the block are put together.

So it’s not a flaw or a casting mark or anything of the sort. It’s a crack.

I have dry and wet mag’d so many parts I can’t count them. That’s a crack.
