Milage on blown engines?

[CptSumTingWong]

I don't have any hard data but it seems like a lot of people with blown engines have it happen under/around 10k miles. I know there's not a lot of higher milage GT350s out there but is it one of those things where if it's going to blow up/consume oil it's going to do it early and if you get past a certain milage mark your particular motor is probably in the clear and will last a while? Or is there higher risk of engine failure with more milage as they wear and deteriorate? Or is there no rhyme or reason to it and sometimes they just kaboom?

Do a search. There’s threads at nauseum about this.

My unscientific data, just from reading many, many threads, is that it has happened with cars as few as a couple hundred miles, to over 20K miles.
I've always believed that how you break in the engine during the first 1K miles, plays a significant role. That being said, some engines are just inherently defective, or poorly built. Case in point is the 2020 model it looks like you own. They have a timing chain tensioner service bulletin for those cars. The possiblity exists that the timing chain can jump the gear, and damage/destroy the engine. I hope you had yours checked.
