@HRVAT1975 Anything over 150k. A rebuild is usually done at 100k to make sure it's still running healthy. I had a 110k mile 98' LS1 driven fairly hard, not sure if it was rebuilt at 100k because it threw a rod... on stock power! So I'd say rebuild the motor for sure at 100k just to be safe if you're going to be driving it hard.
what do you think would be considered high mileage for an ls1??? in general, not knowing how the engine was treated/driven.. Thanks...
