might wanna check the oil screen in the pan for timing gear teeth & valve stem oil seals
 
those may need replacing too

Alright, was on vacation for a while so i couldnt get back to you guys but heres the news.Finally got to stripping the motor down. And i found the issue... Nastiest blockage ever. Just rock solid. 
Took me forever to get it cleaned up nice. A little scared that the motor might have some spots like this... But ill be able to see it when i take the heads off to do a gasket swap. 

Thanks for all the help guys! Big smile

Haven't heard from you and your problem came up again earlier. Another suggestion was to check your vacuum advance vacuum. It runs off an amplifier and if it's not creating the proper advance, coolant cavitation can begin around the intake and flow when the thermostat opens. Usually a cold start problem but a problem that prevents getting to a properly warmed up engine. Easy to check with a vacuum gauge.

If you use a 16 pound cap it will also increase the cooling system pressure against the radiator cores and radiator tanks, the cooling system gaskets (such as head gaskets), the cooling system seals and the cooling system hoses. When compared to using the 13 pound cap.

If you use a 16 pound cap it will hold three additional (more) P.S.I. of pressure in your cooling system, than the 13 pound cap. It might be worth it to try. But it still might not stop the geyser that you are experiencing in your cooling system.

Going to remove the intake manifold too see if i can see a blockage somwhere. But before that, does anyone think that raising the rad caps psi from a 13 to 16 is a good idea? Maybe the system is just higher pressure than the stock 13?

FWIW the Cold line only comes into play after the system has been purged. there may be an air pocket in there causing the excessive T-stat heave? after sitting for such a long while there may be scale blocking the head gasket passages helping to contain an abnormal air pocket. this reminds me of an old thread on the old Cleveland board, same story ... long storage and his was actually overheating but nothing he did from the outside made any difference T-stats water pumps radiator nothing helped until he tore into it to find scale blocking the head gasket passages
 
i found the conclusion too bad the pics died but what he's describing is that the holes in the block deck surface were blocked with sl*g that he dremel'd through http://www.network54.com/Forum/119419/thread/1065402298

Yea the backing plate lines up properly. Nothing seems out of the ordinary. I hope all this is just a radiator blockage and not an engine blockage.

He said that he went and got a new rad cap, hoping this was the problem. He jacked the front end up and filled it up with coolant to the cold line. He started the car up and let it warm up with the cap off. No issues/bubbles/spraying out... untill the thermostat opened up. then all hell broke loose. Just started pouring out the rad. So he slapped on the new rad cap and within 1 minute the cap opened up and it let the water out. About half of the radiator worth.... The water wasnt even very hot coming out. No steam or anything.

Your water pump is a clockwise rotation water pump.

at first it looks like the typical thermostat opening heave until quite a bit too much blows out the hole
 
spew is a fair description

There are  couple-three different plate water flow hole patterns, and the back plate has to match your timing cover.

There is a picture below of the type of water pump inner blades/vanes that you have. They appear to be for a clockwise rotation. Maybe one of the other members will know if they are for sure.

That appears to be a stock (non-high volume/non-high flow) water pump. They are used on 1970 through 1977 302's. They might have been used as late as 1982 on some engines. The inner water pump blades/vanes appear to be for a clockwise rotation, but I am not 100% sure about this.
 
The part number says that the water pump is from a 1977 ford truck such as an f-150, f-250 or an f-350. But as another member said it might have been replaced at some time in the past.

there should be a back cover on the water pump. Did you take it off? It's holes need to be the same shape and orientation as the water ports in your timing cover.
Your fan is the right direction for non-serpentine.
I took my radiator cap off and played with my car, and I can't duplicate the Volcano. It will "Burp" a little after the thermostat opens if I open the throttle and then let off hard, but not much.

Jordan,
 
I understand that much of what I wrote has nothing to do with your immediate problems. It has more to do with your comment about the car history with cooling difficulties.
 
About the taper. Look at your video at 15 seconds. The see through blur of the of the running fan blades can be seen right at the top of the screen. The taper, getting smaller is towards the radiator. Typically the taper, a getting smaller profile is in the direction of air flow. I don't pretend to know a whole lot about these cars so what is typical for me may well mean nothing with your car but I would make sure.
 
I picked up George Reid's book on small block Ford's the other day and in it he writes about water pump casting numbers and states to be careful when using them. Apparently there are a fair number of companies the rebuild the pumps to specs that aren't consistent with the original to improve cooling. People do this to keep the original parts on the car while achieving the better specs of aftermarket options.
 
A last reminder, if your car has the plastic flex fan there should be no shroud per Ford, but some say it should anyway. I'm told Ford says no because the angle or pitch of the blades changes with the RPM's and the shroud screws with that. Your car has no air so as I understand it should have a shroud but if the fan came with the engine, who knows?

Another odd thing, your radiator cap is on the suction side of the radiator, hose is at bottom and goes to water pump. Cant figure out your volcano issue. Water is going thru the radiator, but not back to the water pump. Serpentine belt fans are backward from v-belt fans, so using the wrong fan will push air back instead of pulling air thru the radiator.

Next, you will have to click the browse button to go to the "your pictures" folder to select the picture that you want to download to this site. The browse button is located at the bottom middle of the picture below. The browse button is named Tallozas in the picture below.

To post a picture, you will have to first download the pictures to your phone or computer and put them into a folder such as "your pictures".
 
Next you will have to click the post reply button at the bottom left of this post. Do not use the "quick reply" window/option at the extreme bottom of the screen to post pictures. Because it does not have an insert image button.
