All the 1951 through 1954 engines used essentially the same block and most were either 288 for the cheapest models to two different 327s for the rest. One of the 327s had 5-main bearings and came with either solid or hydraulic lifters while the other 327 had 9-main bearings and as far as I know always had hydraulic lifters.

That said, there were different cams and cranks but, as Packard made their own engines, you’ll have to bore, mix and match whatever you need from those available so you may need other engines which would be cheaper than buying the pieces separately. Better still, just buy an engine that already has the bore/stroke needed and rebuild that!
