If I was a buyer, pulling the pan and looking at the rods, mains and pistons would be the first thing I would want to check out.
That way you can be more upfront with a potential buyer with more info on the condition of the engine.
Pull the pan and pee oil the bottom of the pistons for a few days.
Then see if you can get it to turn, to get a good look at the cylinder walls.
A buyer will want to see the inside and then make an offer.
Not looking is like rolling dice, when buying a non running engine.

Just my 2 cents.
