I didn't take the time to consult Brian's excellent RPO (regular production order) codes, but as I remember, there is no code for dual 4-bbls on any model other than the Caribbeans.
Actually, there is no RPO code for dual 4-bbl. equipment for any model. As a matter of
regular production, the dual 4-bbl. setup was only installed the Caribbean engine (55-56). As such, there was no need for an equipment code.
Notice also that there are no RPO codes for ANY of the engines. Unlike other automakers, there was no choice of engines offered for a given Packard model; engines were specific to the chassis/model - at leats for 55-56.
Though a
Jet Streak performance package, including the 2x4 set-up, was planned for the 56J Golden Hawk, it died on the table - was never available.
IF the factory installed the 2x4 setup (or even any alternate engines) in any other car, I suspect it would have been noted on the production record. I'd bet there would be a "REQ" number in the string of option codes - as Randy Berger found on the production order for his specially equipped Patrician.
(Now, if only the request master file had been saved and would someday surface.) I'd say that, with all other things being equal, a coil mounted incorrectly would be a pretty good indicator that the 2x4 installation was not done by the factory. I'm sure there was sufficient profit motive and parts available for a dealer to install the equipment on any 352- or 374-cid mill, but the conversion could have also been accomplished by some previous owner.
