So, after a complete teardown of my junkyard 5.3 I've measured the bores after ball honing. Im 0.0015 out of round (1.5 thousandths) and the piston to wall clearance is about 0.005. New standard pistons should bring it down between 0.002 - 0.003 but thats the best Im gonna get before having to go full bore and upsize and rebalance at the machine shop.
Anyone here think 0.0015 out of round is a problem? New pistons (hypereutectic) and send it?
