Boring either a 1955 or 1956 352 +0.125in is no problem. If you want confirmation, have the cylinder walls sonic tested for thickness.

Here's the magazine article on the 56J bored to 414CID. Lesser stroke would give exactly 400CID obviously.http://www.1956packardpanther.com/PV8C/HRM195702A.html

Bring your wallet because you will need custom pistons and crank at least.
