I did expect to see the water pump impellers rusted off as mentioned but surprised to see everything there. If got replaced anyways. More surprised the previous owner/mechanic left me a broken off wp bolt in the block (even start drilling it). I tried torch and easy out, nope. Ended up drilling larger and larger til I got what was left to come out and cleaned up block threads. PIA by the way.
I just replaced tstat last week and it looked like this. Took about 10 minutes of running water through the passages to get it to run clear. Then moved to the heater core to flush, flushed the radiator too. Pump pump back on and ran it with the water hose on the inlet (don't laugh at my setup, it worked). Took about 12 of those smaller buckets full to get to start running clear even after all the previous flushing. Anyway, buttoned and filled everything up and so far so good.
Also had a rear door handle fall off which seems fairly common. Trying to save some money I made some walls out of tape and poured some epoxy in there good as new.
Still not sure why the "coolant" was so nasty. I'm thinking they filled with just water and no antifreeze could be a reason for all the rust.

Whats wrong with what you did, nothing to laugh at lol? Im the one who suggested you stick a hose in there and flush the crap out if it. Then flush with distilled to get most of the hose water out. Then mix your coolant and done.
Im glad you got it clean. How are the temps looking now ? Onky thing i hate about these amc engines is how the water pump bolts also hold the timing cover on.. if youre not carefull you lose the coolant seal between the block and timing cover.. i did.. and it leaked coolant from there.. had to tighten the bolts to APE tighteness for it to stop.
I would keep that old pump as a spare in case you need something for an emergency.
