GEN 2 Engine casting - please tell me this is normal

[RBA]

Hi Gents,

I realize that engine blocks have a rough finish but my block has these cracks showing. It is so rough that it will cut your skin. Is this normal? Please tell me yes...

Normal. If the “cracks” are above the surface then it was from molding.

I work for a company that may likely have supplied the metal to cast that block. That does not look ideal- shouldn’t have left factory like that, could be a casting issue- could be an alloying issue too much SI too early can cause “wrinkling” like that- it’s not ideal, but shouldn’t be something to worry about in terms of failure. It’s more cosmetic.

My ‘19 looks pretty much the same way. You couldn’t sell a performance/race block looking like this, but apparently you can in a 70k truck. Kind of like pot metal.
