I knew as soon as I left for work that I forgot to divide by 2. That's what I get for being in a hurry.
Anyway,
Cylinders
1-.149 + .102 = .251"
3-.154 + .102 = .256"
5-.137 + .102 = .239"
7-.087 + .102 = .189"
I thought you were to get .250" (or whatever it was) at the cast bore size.
If you wanted a 4.375" bore, they cast the block at that bore size with the .250" wall?
So if I had an IA II block with a 4.170" bore I can bore it to 4.375" and still have .250" or more?
The Brinell stuff, I'm not touching.
I'm not convinced it would be a problem.
