Not quite correct on that last.
Packard 356's were last used in '50. They were the last of an older large series.
The existing small 288 was enlarged to 327 for the higher end cars in 51. In fact it came in two versions, 7 and 9 main bearing, depending on the "prestige"/wheelbase of the car.
In 1954, the 327 rec'd one last increase to 359, where it came with a somewhat troublesome aluminum head. The rated power was 212.
The Packard v8 arrived the next year, 1955.
Not bad for a 34 year old eh?
