It is my sincere wish that other people are learning from my mistakes,
and can therefore save themselves a bit of money and bother and not
have to make mistakes of their own to learn by.
One of the biggest things I seem to be learning is how expensive it
can be pushing the edge of the envelope. Not so much because the parts
are so much more expensive (though they can be) but because of the
number of those expensive parts that you end up having to throw away
because they went just a little bit too far.

That was pretty much what I expected, and in the long run isn't that
much more work or expense, but I can always hope that I'll get some
small break where doing it the right way is doing it the easy
way. Then again, I guess I can hope that someone will drive by on
highway 9, see me working on my car in my pitiful tarp walled shed and
decide that my project is so cool that they need to give me large
amounts of money so that I can do it right.

Theoretically they are 8.0:1
This time, I'm getting burette and will measure the combustion
chamber volume "cc the cc".

That piston is going away. I'm pretty sure that those nicks are caused
by bits of ring.
While I'm replacing the rings, should I get new rings from Venolia, or
is there some specific brand I should get?

Girling is not a verb.
