Jerry,
As much as I hate to say it, I would source another block at this point. Mon=
ey wise, a good block would be much cheaper than any machinist cost. Bad new=
s obviously is that Guy is going to have to pull the entire engine.=20
Guy, it=E2=80=99s too bad you live so far away as this would be a great grou=
p effort to get your car fixed!

I've got pretty good confidence that someone near you has one or two
engines sitting in a corner in their garage (me -- 4ea. TR2/TR4  2ea  TR6)
:)
 I bet it wouldn't be hard to find a block if you put the word out.

That said....  I like keeping the original engine if at all possible.....

I would find a metal block with a hole to use as a drilling guide and it
will likely drill ok --- Where I fall short is getting the tap started
perfectly straight, but it would likely correct as you tap deeper.

I'm lucky to have a very good cylinder head shop nearby that will also deck
blocks and do repair work like this at a reasonable price.

Good luck!
