IML: '56 & '57 Chrysler and Imperial Engines

[Joe Strickland <jwstrick426@xxxxxxxxxx>]

I can vouch for the fact that a '56 Chrysler Windsor had a 333 cu. inch polyspherical combustion chamber engine.  The New Yorker and Imperial had the 354 cu. inch hemispherical combustion chamber engine.  In 1957 the New Yorker and Imperial had a 392 cu. inch hemispherical combustion chamber engine.  The Chrysler Windsor and Saratoga models had engines of lesser displacement and were not hemispherical combustion chamber type.  I don't remember the displacements for the Windsor and Saratoga for '57, but it was not 318 (which would have been in a Plymouth or Dodge).  I believe the displacement on the Chrysler Windsor engine of 1957 was at least 354 cu. inches or perhaps 360?  Perhaps someone else can weigh in on that issue.  I know the Chrysler Windsor and Saratoga models still had the polyspherical combustion chamber design with spark plugs entering from the side of the head more akin to the later 318 and 413 engines.  The early 318 (1955-?) was a polyspherical head design while the later ones ('59 & up?) had the wedge head type design.

In any case the Imperial line always had the hemispherical combustion chamber engine from its introduction in 1951 through 1958.  In 1959 the 413 wedge-head engine was introduced in the Imperial as well as the Chrysler line.  By then the Chrysler Windsor or Newport(?) likely had a 383 cu. inch engine.
