The fact that they made all those pulls on a 4.8L instead of a 5.3 may have something to do with the survivability since there is much less torsional load on a shorter stroke. Nice numbers for sure.

Don't forget either that there is no telling what the bearing clearances were worn out to. Short stroke motor setup with loose bearing clearances with the proper oil selection will be hard to grenade. The stock pistons are harder than most forged pistons and will generally take more to break. However, when they do break they grenade into lots of tiny pieces. A forged piece will generally just deform and stay together. I think this could be a fun way to make tuns of power in a weekend car. But not in my DD!
Gotta to give the little 4.8 lots of props for that many runs at that HP
