The owner supplied the belts however they are all over eBay. To set the timing properly you'd want to have the distributor set up on a timing fixture. These 6's are a challenge but unique and they drive really well.
Is you heat rider valve in the exhaust manifold functional on yours?

From your description it sounds like Skip rebuilt your pump?? Also is
the radiator full of coolant and does it stay full? Losing coolant through
the overflow tube is a common problem. If your radiator filer neck is
set up for a 4 lb pressure cap that will prevent coolant lose below 205
degrees. Modern stats restrict the flow of coolant through the engine.
Remove the stats until the problem is resolved. Fix all the known
problems you have found. Then to test the system put a house type
box fan against the grill and run at an engine speed of about 25 MPH.
Take the temperature with a laser pointed thermometer just below
where the upper hose connect to the engine. Take the temperature
at that spot every 5 minutes and write them down. After about 30
minutes the temp should stabilize and that will be the temp you will
see driving. In heavy traffic on hot days or long idle periods the fan
may not produce enough air for cooling. Purple Ice is a wetting agent
and two bottle should reduce temperatures about 20 plus degrees.
This can be added to your antifreeze. G.M.
That proves you have a fan related problem. It will rise without the external fan
but does it go over 205?? G.M.

yep, it will actually percolate if i let it
How long does it take to percolate after you took the fan away. And what
temp is percolate? Most old Fords will get almost to the boiling point in
hot weather if left to idle for long periods. There is a trick to driving these
on hot days. You try to keep the speed over 25 MPH, if you get stuck in
traffic you got to get out of traffic and get moving. It will come back to
normal in a mile or so. I can remember lots of times I had to get moving.
One time it was over 100 on I-75 somewhere in South Georgia. Temp was getting up a little over 200, I went down the right shoulder passing 50
or more cars and got by the pack, the temp came back to normal and
I tried not to get into that situation again. This was maybe 15 or more
years ago going to a National V/8 show. When I got there and stopped
I experienced the first vapor lock I remember having. This may have
been when corn gas first came along. G.M.

GM. It percolated on me one day when I was stuck in traffic. It has never percolated on me since. But I have never been in heavy traffic at a crawl since that day. With the makeshift fan shroud I had on it it idled for over an hour and never got above 192 or so. So my theory is make it complete fan shroud and I should never have to worry about overheating again, stuck in traffic or not
The shroud is the solution. You are not getting good temperature readings.
At 215 it wouldn't be percolating, all the coolant would blow out. G.M.

Did you ever resolve this issue? Also, I think my car could benefit from a Six Bladed Fan.. when I checked Macs & Carpenter, came up with only electric (ugh)... I love mechanical fans..

Kinda sorta tried it tonight. I did drive it and let it idle an hour an the temp never got over 190, that's the stat i have in it.The kinda sorta statement is because it cooled down here to mid 70s tonight. I am taking it tomorrow to a local car show, "Cruisin the Heartland" in Elizabethtown, KY. We'll see tomorrow how it does.

There are no timing marks. The distributor has to be set up on a Distributor machine to get it dialed in. Otherwise your just shooting in the dark.
