1) rebuild original engine if you have it
2) replace with an original era engine that you rebuild
3) if $ not an issue - GM crate HT383
4) if $ yes an issue - GM L31R

Between the last two, L31R is certainly the most bang for the buck - a great upgrade and less than half the price of the GM HT383. I like the HT383 because, well, it's a 383 first off - but also allows a mech fuel pump. Not a big deal at all to use the electric fuel pump on an L31 though - it really is the best way to go unless you indeed happen to have money coming out of your ears and don't know what to do with it.
There are other builder crate options for 350s and 383s, but, well, there you go.
