Hydrolocked
Project 73 390 FE truck I had out front got hydrolocked from tropical storm Nicole this past week.
When it wouldn't turn over I pulled the plugs to discover a lot of water. Spun it then to push the water out.
Then drained the oil. There must have been 4 gallons of water in there. I literally had to dump the pan because it was all water and then had time to move the pan back in place because it was pouring water the whole time.
Cleaned the carburetor out. Then it started right up and I drove it across the yard. Seemed okay, but of course I have a lot of white smoke now. I let it run for 15 minutes then shut it down for today.
I have no idea how that much water got in it. The carburetor was left uncovered along with the hood being off, but I did have a car cover over it... apparently it isn't water proof.
What do you think? Is the engine pooched?

I would also check the gas tank. Or at the very minimum if you think the tank maintained its integrity, add some fuel additive that’s designed to absorb moisture to let it burn in the combustion.
In liu of that you could simply put some rubbing alcohol in the tank.
Alcohol and water combine and then when it gets sucked into the carburetor will burn with the fuel better than just water and fuel separate.
I would also put some “snake oil” in the crank case.
An oil additive that dissolves varnish and deposits wouldn’t be a bad thing to have in your oil right now.
Maybe even a new PCV valve or just make sure that the old one is sucking good vacuum.
then just drive it! Keep it running as much as possible and get it all worked out.

I'll pop the valve covers off and have a look if everything seems to be moving right.

We used to run in the rivers, sank the truck several times. Start it up let it idle, remove valve cover caps and dipstick. The oil may be milky that you see in the valve cover. let the engine warm up (may have to let it run for quite a while) and it will evaporate the water out of the oil and go out thru the valve cover. you can actually watch it change from milk to oil color. After it is clear, change the oil and filter again and your good to go.
Have done this to our river truck several times and never hurt engine.
Be sure and check the fuel tank like 1TonBaseCamp said if it was in a flood.
