6.2 High Mileage Club

I put 200,000 on my 2012 5.3L trade it in on my 2019 5.3L 8spd Denali 

But that is an LS based motor, not an LT. The LS engines are a different (arguably better) animal. They routinely go 300-400,000 miles with cheaper easier issues. The LT 6.2 is a hot rod but LT based as it be its not as durable or long lasting as an LS. There are high mileage ones but they have not faired as well as the LS. Just has more going on and more issues long term .
