99/00 engine ran with no oil, usable for rebuild?
I'm looking to build a an engine with forged internals and I have found a '00 engine. However, it was run without oil for some period of time, long enough to develop a noise, from the bottom end (supposedly). It is just a bare longblock (block/head/valve cover). No fuel rail, intake or exhaust.
Is this worth buying and at what price?
I can inspect it and disassemble it a little if there are any checks I can do, short of tearing it all apart. I do not have enough experience with what actually fails under a low oil condition, I can imagine that everything is suspect.
I will be replacing the rods and pistons. The finished engine will live in a '99, with an engine that runs great so I can steal parts.

Pull the cam caps. If it was ran with no oil (depending on how long) it would damage your crank and cams which are your main worries right now. The cam journals may be so wore out that the head is trash.
Do as Savington says, pull the caps and see how your crank is, both main and rod caps, and don't skip one before buying bearings! Check them all out and be 100%. Don't ask me how I know this.

Polishing won't take much off of a crank, it just smooths out the crank journals.
If a crank has scarring, it's not worth using in my opinion. We have several cranks just laying in the shop (chevy 350's)
If the crank is good I usually use like 2000 grit sandpaper, with chemical solvent used a dealerships, and wet sand my crank journals. Not as good as polishing but it would work if you planned to just throw together a rebuild.
