Most mileage from a 5.3?

Ok, you've gotten me off my lazy ***!!! Calm down
Here's the pics I had on my camera phone...I've got a new pic at 541,xxx on my digital camera, but I need to find the chord to transfer the pics.

Dude... GM engineers say you're just breaking an LS-based motor in at 100K, and should see well over 250K before any major issues (if any). My motor proved that to not be 100% true, but that's their story & they're stickin' to it.
Now, I will say that all cylinders aside from the #7 that bit the dust were EXTREMELY clean as if the motor had never, EVER run before. The supporting components (rods, bolts, etc) may not last, but the block is great. I have witnesses that can attest to that.

276k here and I thought I was doing something. Trans went out at 202k and fuel pump at 175k. Also the waterpump went out at 250k as did the alternator, but other than those pretty minor things the truck still runs like a champ. 541 is insane.
