Eric gave you the specs and that would be the optional larger engine for the super.
Build sheets, when found, have been reported in many places. 54 production seemed to favor around the glove box. Look and feel carefully around or on top of the metal enclosure surrounding the glove box. It is most likely just a narrow strip of paper in pretty sad shape taped on. A square label type has been reported glued to the drawer itself--although that one was not really a build sheet but does have the numbers. Other locations some have reported finding one are under the rear seat, or slid in a crevice between the quarter panel and inside fender structure, or stuck between the vent tube and gas filler near top of gas tank.
The fabric on some models was called nylon matelasse--although from the tear in drivers seat, that looks to be a seat cover over the original striped upholstery. The lower end cars used ordinary fabrics with the nylon reserved for the more costly. It was a popular custom of the day to buy a car, put on a dealer supplied accessory or buy an aftermarket set of seat covers. There are several suppliers who deal in the older fabrics so you might get lucky.
Suggest you download the 54 fact book
https://packardinfo.com/xoops/html/downloads/SalesFactBook54.pdf as there is a wealth of info in it. The body section gives the rundown on upholstery. Of course, most of the other manuals are here as well.
