Re the 7# radiator cap and going to a higher one. Packard in 53 did change to a 12# on seniors (part 377264) and then across the line later in the year and made that change retroactive back to 51 on cars where there had been repeated episodes of coolant loss.https://www.packardinfo.com/xoops/html/downloads/SC/SC-VOL27NO2.pdf If you can find a 12 with one inch drop, that would be a proper option if the 7 still has a problem and everything else is in good shape.
