The block was baked, then shot peened and then blasted clean. That

bored to .0028 over so we could see if that would take care of any
cylinder irregularities. It was obvious that the rough bore had
cleaned up the cylinders so we settled on pistons that were a standard
.0030 over. I got those from Wiseco, the company that makes pistons
for a huge number of vendors including many Detroit automakers.

My apologies. I don't use a micrometer much and every time I do I
have to study and learn it over and over again.

I meant to say that the cylinders were rough bored to twenty eight
thousandths over, then honed to the final size which incorporated the
sixty thousandths piston clearance.

If that's .060" clearance, then that's what I meant to say.

I always read those numbers as first place to the right of the decimal
as tenths, second hundredths and third place thousandths.

So is .060" reading 6 hundredths, or 60 thousandths. Or are they the
same? It's always been a mystery to me.
