Was not planning to bore for max. I was trying to get some opinions on what was a safe minimum for wall thickness.
The shop that tested my block said it could go 080.
After some of the replys I don't know if it would go .030.

top to bottom
#5 is fr .142, .152, .141 valley side .226, 227, 251
rear .128,143,159 outside .163.168.184
#6 is close to the same measurements

From Moper's preferred numbers in post #6, you can almost meet his numbers everywhere for .020" . If you can have the bore shifted off towards the valley side, then the numbers say you probably could go past .030" and still meet those minimums. (IMHO, I get the impression that Moper does not take un-necessary chances with machine work....)
