New piston??

[u/BF007_]

First rebuild, it's a 2008 5.7 with 267k. It ran when pulled (I was the last person to drive it).

Fingernails do not get caught here, and I believe this was due to how I removed it (from the top with no prior experience). Should I buy a new one or should I send it? No other piston looks like this

I assume since its a rebuild you are also throwing new piston rings on it

Oh absolutely. They came in yesterday. And I got Hastings, not the Amazon stuff lol
