The only thing I know of is 68-75 had "Powered by Ford" stamped in to the valve covers. I'm not sure of the years except late 60's, Ford made some 289's that you can only tell weren't 302's by the VIN, build sheet or taking the engine apart. Possibly someone else knows the story behind this better than I do.

The block casting number is right where tha starter bolts to the block at the transmission bellhousing. You will probably have to remove the starter to see it. The green arrow points to the casting number.

To find the casting numbers on the cylinder heads you might have to remove them. They are on the underside of the cylinder head, on the intake side in between the pushrod holes. The yellow arrows point to the casting numbers.

There is a picture below of the casting number.

Been soaking the radiator in vinegar and drano trying to get stuff out. I think some did come out. But heres a video on what exactly is happening.

The location of your fan and shroud is wrong but your fan? You can see the outline of it running. Usually on a fan, the blade taper is in the direction of air flow. If your fan is typical then you are trying to push air back into the radiator which is backwards. Look at the top of the profile of your moving fan in your video. It should be pulling air through the radiator. It's possible I suppose that ford just turned the fan blades for CW and CCW pumps and you have just the CCW fan on a CW pump. 
 
 
Your fan should also be much closer to you radiator. That's a spacer problem. My understanding is that without AC and with a shroud the fan should be completely inside the shroud.
 
I'd also ditch the vinegar. Drain the radiator and start boiling water. Use your biggest pots and refill a cold radiator.
 
Your flywheel and pump pulley's should be darn near the same size. It could be the side view optics, but I don't see that in the video. If your motor is physically incapable of accepting the pumps rate it usually results in cavitation. This would not be the typical scenario for cavitation but when high and low pressures are opposite of flow cavitation results.

I see. The taper points towards the engine so its pulling air thru the radiator and over the motor. As for the fan it could be pushed forward a little more. But thats the least of my worries right now. 

Now that you mention it the pulley for the waterpump does look a little bigger than the inner pulley on the crank. But its hard to see. 
Id post a photo on here but im not sure how exactly.

the fan to shroud didn't look too bad, half of the blade pitch should be at the edge of the shroud ideally, the surging up is normal for the first time filling the system before the thermostat opens and all the air pockets are out... but that sudden geyser Shocked WTF??? ShockedShockedShocked

Is that a high volume/high flow water pump that is installed on your engine? It might not make any difference, but it might help the other members solve your problem if they know about it. Some water pumps have a part number on them. If yours has a part number you can write it here.

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.

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.

When the picture loads up on the screen, such as in the bottom right side of the picture below, you will have to click the OK button on the bottom right side of the screen, to post the picture in this thread.
You can repeat this process several times for all of the pictures that you want to post in this thread. Then you will have to click the post reply button at the lower left side of the post to post the pictures.

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.
The above post should be read in a "Grumpy Old Man" voice.

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?
