Welll, I have a few very small (and hopefully minor) things to iron out but
I think I can successfully close the book on this little story.

I spent yesterday tidying up all the wiring in the engine bay and making
sure everything was neatly tucked, zipped, or somehow secured. I also
installed the Go Westy brass fittings on the plastic coolant pipes (fronts
only) the ends had split and were causing a leak. Messy job but a good fix.

So in the end here is everything in a list:

*Installed "new" known good 2.1 engine  that sat for a while but had fairly
low miles on a partial rebuild.
*All new fuel lines and hose clamps
*replaced oil sensors
*replaced coolant pipe from pump to t-stat housing
*new t-stat housing
*new t-stat
*new Temp and Temp II sensors
*Replaced oil cooler O ring
*Replaced screen, filter, and pan seal on trans
*All new botls at engine and trans mounts
*Relaced Distributor with a known good (one that was there had a broken wire
connection on the Hall Sensor)
*New plugs, wires, cap, rotor
*Cleaned all grounds
*Replace ground "strap" from body to engine
*Repaired multiple wiring connections (adding new ones where necessary)
*Re-greased the CV joints
*New Accelerator cable
*New Coolant manifold
*new hose from PS head to coolant manifold
*New oil breather hose
* "New" complete S&S exhaust (I got it for a steal)
*Added an O2 sensor (i never had one because of the old "custom" exhaust.
*Repaired leaking plastic coolant pipes in the front
*Cleaned and painted many parts in the process (although not as meticulously
as I would have liked to because I needed to get the van back on the road).
*Ran for 300 miles - changed oil and filter (adding some Marvel Mystery Oil
this time).

I think that covers it. I'm happy to be driving good ole Grover again. I'm
still hyper vigilant and a bit uneasy about the new engine - I'm sure it's
fine but that overheating of the old engine was traumatic, costly, and a
long road to fix.

Thanks again to everyone on the list for your help and advice - thanks also
to Larry Chase, Pete O, Scott Hengert, Roger VanTill, Benny Boy, Billy Hirt,
Brien Dews, Bus Depot, Vanagain, Go Westy, Frank Condelli, Greg Potts and
anyone I happened to miss.

OK, I'm going to go for a ride :)  Happy Sunday everyone!
