Orphan Part 2 .... Yikes!!!

Me and Pops just watching it and he said it best. Baptized, but probably partially submerged... You may want to check the transmission and axle oil, too. There's some pretty big flooding in your part of the world on occasion.
There has been some areas of flooding for sure. I doubt it's been dunked, but checking the other fluids isn't a bad idea....

was there no pcv system working / seal the engine back up tight and hook a vacuum pump on the dipstick tube and let it run for a few hours
Very good thought on the PVC system. Supposed to be new (remanufactured) engine, just a few thousand miles on it. He has the PVC system hooked in with the brake booster and another vacuum hose - all in "T" from the back of the carb.

Well you have a table to have a snack at while you figure things out. So that's pretty sweet. Odd some parts look really clean, like a fresh build. If you live in a humid area hat will happen but that white stuff is odd. It almost looks like Lubraplate assembly lube and has about the same viscosity. The coolant looks OK.
The table makes everything better .. LOL. It is a fresh engine, the previous owner bought it from Triton out of Florida. And yes, the coolant looks great.
