Is it possible to enlarge the bore of an m30b30 (3.0)
from 89 to 92mm (effectively making it a 3.5, when combined with an 86mm crank) or do m30b34 and 35 blocks have a different cilinder casting (providing more "meat" to the cilinder walls.)
Reason for asking is that the m30b34 block I have needs oversize pistons which are unfortunately made from unobtanium, but I have two m30b30 blocks in good condition, to which I could fit the pistons and crank from the 3.5. I am good buddies with a machinist so the boring costs are not a problem.
Could those answering please focus on the question at hand and not on the why or better this or that, just: can it be safely done?
Thanks for your advice,
Roger
