Well guys, my 4-53T lasted about 600 miles before it failed. Turned out the engine was worn out and had sat outside for years in the Florida weather before it was brought inside and revived. Later sold to me as a good running Detroit where it sat in storage for another 10 years before I finally found a new home for it in my 2009 F350. Overall it ran pretty well only showing signs of trouble on long hills at 30 PSI boost where the blow-by was bad. I figured a rebuild was not far away, but an old Detroit mechanic I know said it just need a really good pull to set the rings, so that what I did. I went on a 5 hour road trip will lots of hills and it failed on the way back climbing an 8% grade after 5-7 minutes. Post inspection showed an engine that was totally trashed, amazing it ran as well as it did. #2 piston seized and broke the liner and that was it. I'm now in the process of building it up as a Silver Series with Ceramic coated pistons, new performance cam, new crank, rebuilt head. Happy time ahead.
