Stuart,
Thanks for the feedback. The engine has "only" 110K miles on it. My first
step is to drain the MMO and replace the oil (what is the STP product that
you are referring to?). Thursday I will install the Oil Pressure kit.
(Thanks for the point to the archives for your oil discussion, those PSI
values will be very helpful.)
A new engine will probably be a Boston Bob version. I'm inclined to go this
route and pay for the installation only once. (I'll be doing lots of
archives research on rebuilt engines in the next few days!).

P.S. Is the "scrap metal" the block or the body panel on the van that gets
bashed when the rod comes through? LOL!
