I rebuilt a 283 back in the 1990ies, simply because I had the engine, and it had
never been bored and crank was at factory specs..The best I can recall I put
327 heads on it, put in a little 268 comp hydraluic cam and lifters, with a 600
edlebrock carb. I ran it for a while, then gave it to my brother to put in a farm
trk..For as I know he is still running it....It just all depends on what you want.
Like Bruce said, the 350 is a hard engine to beat, and parts are very available.
