Spare engine to rebuild?
There's a guy selling a 7.3 here that was pulled out of a 93 F350. He said it was smoking a bit and that's why he changed it out, supposedly had around 140,000 miles on it when it was pulled. Sounds a little suspect to me.
I asked about SCAs and he never responded directly, so that leads me to my question. Is it possible to determine if there is any damage to the walls from cavitation without tearing it down, or do you have to get inside to see?
He's asking $300 for everything except the starter and alternator. Would this be worth it if the block turns out to be shot? I'd like to get one to rebuild over time as a side project to the other 20 or so I already have.
Thanks!

If you can find an adapter to put air pressure into the glow plug hole, yes you can.
You also have to remove the rockers and fill the block with water.
After all that is done, put 150 PSI or so in each cylinder.
If the water level starts to rise, either a head gasket is blown, the block is cracked, a head is cracked or the block is cavitated.
Caution, when you do this the engine will rotate untill the cylinder is at bottom dead center.
Watch your fingers, toes and tools as this happens.
