	I would recommend you get another opinion. I have never heard of an
engine 'developing' pinholes in the liners unless they have gone _very_ rusty.
Since when does cast iron or even aluminium just evaporate? Assuming the liners
were sealed against the bores nothing could happen as far as I can see. Much
more likely (and common) is that the liners in the newly-rebored 3.9 conversion
will slip. I suspect he might have reservations about honing your block when he
can sell you a 3.9 instead (excuse my cynicism, which is born of experience!).

	Just my opinion, but I've seen a few V8s...
