Looking at the numbers, if used 0.040 sleeves, then the inside of the sleeve would need to be completely worn away plus eat into the block by another (0.125-0.0400x2) = 0.045 inch in order to achieve your 1/8 inch piston to wall clearance!|
My experience says EVERY N-series engine is a mystery until it is opened up and measured :roll:
Now that I am properly attired I will suggest that they do sell a .083 overbore kit to replace the .090 wall sleeves. The piston bore on them is 2.270. So if someone installed stock pistons in an engine that previously had the oversize pistons in it you would be getting close to that .125. But my trusty assistant Watson cautions that there are many other possibilites as well....
