Block filler cracks
It does have a block filler in it, a few days ago I finally started prepping the block for assembly and I noticed that the block filler appears to have some hair line cracks in it. I’m wondering if I should be concerned about this.
I’m really not worried about the strength, having the block 1/2 filled is complete overkill for what I’ll ever put this engine through. I’m just worried if it can have any harmful effects on the engine.

Is what I’m seeing normal? Anything to be concerned about??
Unfortunately I am not sure what brand of filler was used.
I have no experience in this area to answer your question.
Can only offer to refer you to a local machine shop or perhaps email one of this forum's sponsors: Katech.
Once resolved please post your findings to educate us all.
