I plan to tear it down and have a machinist do a rebuild. He has agreed to do
the labor; I supply the parts he needs. However, he wants the pistons free
before I turn the motor over to him.
Top of the motor under the valve/cam cover looks good. The only rust is see
is a spot on the cover about the size of a dime, and it's only surface. I
suspect most cars which are run every day have more. I guess that's a good
sign.
Pepsi contains phosphoric acid which attacks iron oxide without attacking iron
metal. It's the active ingredient in many rust inhibitor products. Thanks
for the advice for a cheap alternative.....

Diet Pepsi. No kidding - google it.
But you'll need to figure out how to clean it out, if you're not
doing an immediate teardown.
I'd also suggest you pull the dizzy and spin the oil pump (CCW)
to get some lubrication into the bearings.
