OK I agree, but if all six cylinders have 70-80 psi isn't there a problem?
I'm thinking the 120-140 psi range is what I'm looking for based of
something I read long ago.
Hence my latest question.

Anyone know what psi reading I should expect on these 1988 200's?
On a new engine?
An engine that I probably don't want?

You should not be concentrating on absolute compression reading, The
compression reading will depend on humidity, air pressure, cranking speed
(battery charge) and a host of other factors. You should be concentrating
on the difference between the cylinders, a range within 5 psi is what you
ared looking for.
