Over Heated

The belt laying on the engine looks like it went around your waterpump and crank. The belt still on it now only goes around your alt and water pump. Sooo, looks like nothing was turning the water pump and your engine overheated blowing out the freeze plugs and locking it up. You did not notice the belt laying there before you started this post ?
Again as already said, something broke and since your son did not notice the steam and the temp gauge, it only got worse.

Like the other posts above....
We see a single belt in the last picture that is only going to the waterpump and over to the alternator (look close). Giver the alternator a spin... ill bet the water pump just freewheels with it... its not connected down to the crank pulley anymore.
The belt that was on the very front of the water pump pulley and went down to the crank appears to have broken ... sooooo.. You had nothing turning the waterpump or alternator for that matter and so it overheated.

I don't think the factory did that nonstandard routing of the belts. The main reason is that there is no way to adjust the belt tension on a belt that only connects the crank and water pump. It was likely too loose and was thrown after a couple of high rpm runs. Minutes later the engine blew.

I think you are right, now that I look closer.

Which to your point... I am not sure how they were adjusting the tension on the belt down to the crank. The picture is not good enough and only the lighter picture allowed me to see that belt routing.

Sorry. I should have said p/s,crank,water pump. The belt that is still on there, is only going around the alt and the water pump. Kinda hard to tell from the picks. Or if the alt has a double pulley that could be possible for even a different routing.

It should have been smoking and spewing water before the freeze plug burst.
Your son should have known something was wrong.
There is a good possibility the engine may not be totalled. If it seized and quit, it may turn over after it cools.
But it will need to be inspected closely.

I am not sure about 74 but 69 doesn't have a light to warn you that you are over temp and unless you are looking at the gauge regularly and know the car well you may not notice the early signs of over heating.. especially if the exhaust is loud and the radio is up. BUT an engine being driven while overheating will loose power and steam etc from coolant blowing over had to be present.
Before you try to crank it again pull the plugs ... you could be hydro locked from head gasket or cracked head.
How did you have the belt setup to drive the water pump? A few of us are trying to figure out how you were adjusting the belt down to the crank or how you are actually driving the waterpump.
