How much overbore?

How much overbore will a Packard 352 engine take? Was the same casting used for the 374? I believe the 374 was bored out to 4 1/8"

Could you get 400 ci out of a Packard block by overboring, or would it have to be stroked?

Just wondering the feasibility of having a Packard "400" that really was a 400.
