It's a "creation". Last legitimate Packard-engined car with supercharger was the in-line 8 1954 Panther which did use a McCulloch unit. For 1956 their "new performance" thrust was was to be fuel injection which was researched but abandoned. No legitimate kit for dealers for a 55/56 V8 supercharger on a Packard block but of course a dealer could have done any thing whether it was factory-authorized for not, they could have put a Cummins diesel in a car if they wished and the customer was willing to pay but you could hardly call that a dealer option.

Prior to the Daytona, the 52 Macauley Speedster was supercharged and there are some very nice photos of that installation courtesy of the Marano Collection. Prior to that the only other legit supercharger installation on a Packard that I'm aware of was the 1929 experimental installation and there is also at least one good photo of that installation.
