> solid with no hint of peeling or flaking inside or out.

Its good stuff.  Dave Williams turned me onto the product, and I coated my fiance's
tempo, my Lincoln, the Buick motor, and coated the 383 stroker as well.

> What's a swirl tank?  If it just "swirls" the water, why?

A swirl tank is nothing more than a round resevior, though they can be in other shapes
I guess.  The inlet to the tank is at the top almost in line with the circumference of
the tank, thus the fluid (water, oil, tranny fluid etc) spins around the tank,
allowing the air to escape from the fluid, and rise upwards, while the fluid flows
down the sides of the tank.  That's all a swirl tank is.  The top of the tank is bled
off (air) to the radiator or other highest point in the system.  For oil, its usually
bled to a valve cover if I'm not mistaken.  I had an oil one lying around, so I soaked
it in parts cleaner and removed any buildup (minimal) and used it simply because it
was available.  You can use any kinda tank you want, and just have to make a pump
setup to match/fit.

> this pretty typical?  Is there any way of tapping either the pump housing

My dodge seems to be the same way.  One option is to tap the pump, thread, and shove
in an AN fitting.  I haven't dared to do this yet.  I'm not sure which way the coolant
goes in the pump yet.  This is new territory for me.

Its key to tap the water BEFORE the engine heats it.  Otherwise you have an intake air
heater 100% of the time.  Coolant as you know hits 200-220 degrees depending on your
thermostat.

> Do you happen to have a 'net source for the pumps?  This is what I had last

I went to a local marine store 10 years ago, bought a 12V plastic sump pump and
attached it to a small hose and a battery on a Boy Scout canoe trip years ago.  This
discouraged younger scouts from trying to splash me.  Short range, but pretty much
constant flow.  I simply recycled the parts to a more interesting application.  Find a
marine store and pick one up.  Though I live on the shoreline, your region might not
have that many of them depending on the sailing ability of said region.

> much engine bay area to work with and I don't want anything underneath unless

That's one of the advantages of my truck - even with a 528 stroker (if I had one) I
could still stand under the hood.  Though if I were to mount a tank in my pickup, I'd
not put it under the hood, but instead underneath in front of, or behind, the side
mounted gas tank, so its not in direct contact with really hot engine heat.  Airflow
under the hood absolutely sucks, though the excessive heat might be the horribly
running 270K 318 that's in there right now, and not a dysfunction of the truck
design.  Who knows.

You have a 1975 Dodge D200 too? <grin>
