Time For a rebuild

Just my luck, I took the 6.1 apart to take to machine shop so we could sonic test the bores. I also took the 5.7 which I thrashed till 2 am to get apart as a backup just in case as I know the 6.1 has thin cyl walls. Drove 4 hrs sonic test the 6.1 and find I have .080- .100 on the trust and.060 on the non thrust side. Even found a .042 on the non thrust side. I new these books were thin but come on. 5.7 didn't get much better with .120 on thrust but need .020 over bore as it broke the ring land and my friend drove 150miles with it like. Since this is getting some boost I don't trust those cyl walls so aluminum block, Scat 3.9 crank and rods on the way.
