Re: Is "all original" worth keeping a 305?
Nothing wrong with a 305. If it hasn't been abused or run to the end of it's service life it'll last just as long as a 350 of the same age and miles. The 400 smallblock is the engine with issues...
If she runs good and doesn't smoke run it. If you need or want more power get a 350 crate engine or a 454 or a 472 caddy or whatever other engine you want and decide to afford.
If she's smoking and feeling her age and you want an easy drop in replacement get a 350... Unless you have to get by the smog Nazis.
