It says 320 c.i. in the description. Is that not correct? BTW: Bob Palma's your man here. He'll know what [u]was</u> original. Think the exterior (blocks) are all the same.

I beleive the Packard V8 was 352 cubic inch,this same motor was also used in the 1956 Studebaker Golden Hawk.

In '55 it was offered in some models as a 320, and other models as a 352. In '56 it was 352 and 374. I'm getting in over my head. Again, Bob Palma can give more precise breakdown. (And no doubt, thoroughly interesting personal stories about each one.[^])

A story about his Patrician. There was 3 Packards in this old store building. The Patrician a 52 2 door looked like the cheapest Packard ever built. And a 49 4 door. The patrician and the 52 were sold. 2 weeks later the old store building burned down and the 49 was still in there.
I posted about the Patrician there was a extra transmission in the trunk. And mam was it heavy.

'55 Clipper Deluxe and Super used the 320c.i.
BTW: I'm getting my info from Motor's Auto Repair manual. I don't know this stuff, just what I read.

I think my '55 Hudson has a 320 packard mill.

Yes, guys; the subject car being sold, a 1955 Clipper Super, would have had a 320 cubic inch V-8, as did the lower-price 1955 Clipper DeLuxe.

Super was the mid-price trim line. The higher trim line Clipper Custom would have a 352 V-8 engine, as did all the 1955 Packard "Senior" cars (Patrician, 400, Caribbean).

Likewise, the 1955 320 cubic inch V-8 was sold to American Motors for 1955 Nash and Hudson V-8 models. While the 320 was available in Clipper Supers and DeLuxes with a manual transmission (Ultramatic optional), all the 320s that went to American Motors had Ultramatics.

For 1956, the 320 was discontinued. All Clippers and American Motors applications had the 352 in 1956, whereas all the 1956 Senior Packards had the enlarged 374 cubic inch V-8, new for 1956. In mid-year 1956, American Motors quit buying Packard 352s and started using their own, all-new AMC V-8.

Curiously, all Packard V-8s have the same 3.5" stroke. Only the bore was changed to go from 320 to 352 to 374 cubic inches.

Now if you really want to stump someone with Packard trivia and win a beer some evening, here's an interesting fact: Packard went to a 12-volt electrical system in 1955 with the new V-8, as you'd expect. But in 1955, the Packard 12-volt system was positive ground. In 1956, they joined the rest of the industry and made their cars negative ground.

That's a bet you can nearly always win; betting some know-it-all that one car had a 12-volt, positive ground system after WWII. I may stand corrected, but AFAIK, 1955 Packards were the only domestic postwar automobiles to have a 12-volt, positive ground system. [8D]BP

Unless the radio is unique to 1955, that will be VERY critical to a buyer of one, as they are polarity sensitive.
