so, when they do score, seize, shrink and do other bad things, then each of you can judge for yourselves if the engineers know what they are doing.

Yes, I read it and you're exactly right that is not what you said "at all" ... but you most definitely implied that tighter running pistons will give trouble. This you post right after I made statements about .0015 clearance of KB Performance pistons.
Apparently you are not familiar with hypereutectic aluminum. This is what is used in KB Performance pistons. This particular alloy has less thermal expansion than conventional piston alloys. The nature of its major alloying element, silicon, at up to 18% acts to keep the heat in the combustion chamber and prevents heat transfer, thus allowing the rest of the piston to run cooler.
