Congratulations and welcome. Believe around 100psi +/- has been given as a workable number for a decent condition engine. Varies a little depending on the compression ratio. Stuck valves are a good possibility if the engine has been sitting a long time.

There are copies of the service and parts manuals on site which you can download. If you want paper then the Packard clubhttp://www.packardclub.org/ has reprints as do the major Packard vendors. The original 46-50 service manual was a small format roughly 6 x 9 inches with 7 individual booklets as chapters. That small size in one volume is the format available from PAC and vendors. For those like me with feeble eyes, I personally prefer a larger format 8 1/2x11 version made available by Faxon Auto lit.http://www.faxonautoliterature.com/1946-1950-Packard-Service-Manual-Reprint-P9235.aspx
