Simon,
Doing it right requires a regrind. Your best bet is to take the whole
mess to a competent machine shop and have them boil out the block and
measure everything. You can then decide with their input how much you
want to put into this engine. Anything else and you are flying blind
with the likely costly consequences. Doing it right means you will
probably be getting to the pub in this car for the rest of your life!
If you are interested in learning more about engine rebuilding the right
way I highly recommend a new video from Eastwood titled "Rebuilding Your
Engine", part #46034 for $19.95. This video uses a small block Chevy
engine but goes through inspection and careful assembly with checks for
accurate tolerance. I learned quite a bit even after 30 years of
amateur rebuilds, and I found it much more useful than the engine video
from Moss, which I also have. The Moss video just has the machine shop
do everything and then assembles the engine. One thing the Eastwood
video does point out though is that this particular mechanic always
bores his engines oversize and fits new pistons and rings. When you see
how much work is involved in a proper rebuild you will understand why it
isn't worth skimping.
