RE: [Chrysler300] 57 Intake question

["Rich Barber" <c300@xxxxxxx>]

The claimed '57 manifold on e-Bay appears to be very similar to the '55-'56
intake manifold with the exception that the little oval plate with two bolts
is just a cast boss on the '55-'56.  That boss may be the base for an a/c
compressor?

The casting number on the bottom of the '55-'56 manifold is 1634285 and
should not be mistaken for a part number.  The parts book shows part number
1731686 for the '55-'56 300 intake (a rather high number for a 1955 part)
and 1733477 for the '57-'58 (non-FI) 300 intake manifold.  Perhaps someone
can furnish a casting number for the '57-'58 manifold so that you can verify
it with the e-Bayer.

I think I have read that the '55-'56 manifolds are not interchangeable with
the '57-'58 manifolds due to differences in the dimensions between the 392
heads and the earlier 331/354 heads.

FYI, the little rectangular depression on the passenger's side of the
manifold is a platform for a stamped steel coil bracket that is fastened to
the adjacent bolts.  There is a threaded boss with something in it in the
e-Bay manifold.  On my 1955, there is a fitting in that boss that provides
access for a vacuum line to the power brake booster.  I have a spare
manifold that came with a temperature probe in that hole, giving rise to the
question that these could be marine manifolds?
