1. How much difference is there between the 54 rear axles and the 55 rear axle IN TERMS OF STREnGTH ???? Were they the same axles????

PackardV8, check the parts book, the 53,54 and 55 senior car rear axles are the same. I didn't check but the junior models may also be the same.

I must admit I can't see an alternative engine, be it a SBC or Caddy or whatever, as a necessity for cruising at modern speeds at 67-70 mph. Later prewar and all postwar Packards are quite capable of maintaining those speeds, especially when equipped with overdrive or Ultramatic, all hobbyists do it all the time. However, to each his own; just don't make that the excuse for an engine swap, do it because you want to, not because it's a necessity.
