| Just crank and rods. |

The crank must obviously be changed.
390 rods are a little shorter than 352 rods, and all since mid1963 are a heavy-duty design which incorporate a heavier H-beam section.
You can also reuse the 390 pistons, assuming they are not excessively worn.
Note that 390 pistons tend to be available in three compression ratio ranges - one for light trucks (pickups, etc) at 8.5:1 (or so), one for most 2V car applications at 9.5:1, and another for most 4V car applications at 10.5:1. Other compression ratios were available from the factory, but this covers the basics.
