Building motor from scratch, where to start?
In my dad's garage sits a rebuilt GM motor block from like the fifties, v8, 264. He says if I want to play around with it(that is, try to get it running) I can. The headers and the gaskets are all still in great shape, being only ten or twenty years old.
What I'd like to know is, after cleaning it up a bit, getting the little rust off of it, where should I go from there? It'd be nice to find that book he was talking about that layed everything out specifically, down to torque specifications...
Anyway, any help, links, etc. greatly appreciated.

That should tell you what kind of block you have, and what kind of car it came in if the numbers are still there. From there, you should be able to get original build specs.

Now are you just trying to see if you can get it running, or are you "building an engine from scratch", i.e. overhauling the engine? All other answers will flow from the answer to this question

If it does have a provision for an oil filter, the cartridge type in a canister, it's probably a 1956 engine but you should still change oil.
I agree with Tim. Get a manual like Motors ot Chiltons (Haynes would be my last choice but would still have enough generic info, most of it correct, for a start).
If it's been sitting in a protected place for 10 years, I wouldn't be afraid to put it in a car and try to start it after removing the sparkplugs, squirting a little light oil into the cylinders, and trying to turn it over by hand. If it's been sitting 20 years, that might be too long to start it without pulling the heads to check for sticking valves and cylinder rust.
Those early 265's had a tendency for piston cracking near the skirt so if you are change your mind to do a total rebuild, figure on a new set. You might have to have it bored if the cylinders are out of round so you would need new pistons anyway. Hopefully the previous rebuild covered that.
My first engine rebjuild was a 1955 265 a long time ago but for the same reason as yours. Just as a learning experience.
Good luck on your project.

Even though the engine was "just overhauled", that was several years ago and lots can happen to an engine that is just sitting and not running. You must disassemble the engine part of the way to make sure that there is no damage due to rusting/corroded parts, such as the piston rings being frozen in the cylinders. You could put something like PB Blaster into the cylinders [via spark plug holes] and try to loosen things up; but that may or may not work. Since you are wanting to learn about the engine anyway, why not take the oil pan off, then remove the lower bearing caps to evaluate the condition of the bearings and journals (and to put some start-up lube on them). Also remove the intake manifold and take the cylinder heads off. At that point you can put the de-rust fluid directly on the rings/pistons and let it set a day or two...then try to turn the engine over by hand (or with a wrench). If it turns freely and you don't see rust in the cylinders or in the heads/valves, put it back together.
You will probably need to disassemble the carb to make sure it isn't stuck. It should get a new needle valve and float as a minimum; if it wasn't freshly rebuilt when the engine was done, you might as well do it now and get it over with. Again, you will be learning all about the engine and how it works. New points, condenser, plugs and wires are imperitive [IMO]; rotor and cap are optional if you see no corrosion/damage.
Get a timing light and dwell meter ready, put fresh oil and a new filter in it, change the fuel filter and supply some gas, then light 'er up! Let us know how it goes.
We'll help whenever you need it. 
[P.S. Make sure you change the hoses and belts before you install it in a vehicle.]

I'm with 63Mako - someone will desperately want these parts and you can likely sell 'em for what it would take to buy a late-model Vortec engine that you can get running easily and learn engines on from a much better starting point.
Not in any way trying to discourage you - just tryin to suggest a path with the best chance of success!
Another alternative is to sell the block & heads, then buy all the parts necessary to build a nice engine...the best of both worlds.
But, if you really want to keep the 265 for yourselves, stick with "Plan A".
Never having actually seen the engine, I too would guess it's relatively valuable. Perhaps someone would be willing to spend a lot of money to buy it. If you'r not experienced building engines, there's a chance you're going to damage it. I'd also second the idea of buying a cheap used 350 and having at it. For a first time engine rebuild, you can do dozens of things correctly, but it only takes one mistake to do a lot of damage/destroy an engine. About 20 years ago, I spent probably $2000 rebuilding an engine that ran about 5 seconds.
