Re: Improving a 283
I think RustyPile is probably kidding, but not all 283 blocks could be safely bored to 4", even when new.
The cannister is part of a crankcase ventilation system, from breather to road draft tube. Google is your friend to learn about it. After a compression check, I'd simply change the spark plugs, oil & filter, and try to start the engine. If no excessive valve train noise, drive it for awhile. Might want to check the carb internals, too. As for 305 heads, #416 and #601 castings from the Z28 HO engines probably work better than stock 283 heads. There's talk about these on Chevy forums like NastyZ28 and GBody.
