1957 Plymouth Directory

The Forward Look

Forward Look was a design theme employed by Virgil Exner in styling the 1955 through 1961 Chrysler Corporation vehicles.

Chrysler vehicles were being fashioned by engineers instead of designers, and so were considered outmoded, unstylish designs. Exner fought to change this structuring, and got control over the design process, including the clay prototypes and the die models used to create production tooling.

Plymouth Belvedere convertibles were only produced from 1957 to 1959

Ceramic coated exhaust manifolds
Cap's Brite Hot Coatings
www.capsbhc.com
Ceramic coated in cast iron color $163

  • 9/21/10 Chromed rear trunk emblem - looks good
  • 9/25/10 I had to take the heads off to remove the old exhaust manifold studs and install new ones. Intake manifold had to come off again.
    Good thing! In the process I found 2 bent pushrods. One accounted for a click I have been hearing. I presume after the engine had been sitting for a long time and they started it up in Salem Indiana a couple of intake valves were stuck due to old varnish which bent the pushrods. Anyway new pushrods are on their way and new studs are installed.
  • 9/27/10 Replaced the fan, cleaned and painted the generator. Brushes are 90%. Old fan was really chewed up..

  • 10/9/10 Installed radiator, heater core, blower fan, generator, ceramic coated exhaust manifolds and horns.
  • 10/10/10 Painted inside of hood
  • 10/11/10 Had a machine shop drill and tap a hole ($35) in the intake manifold under the thermostat housing for the MOON gauges temperature sending unit. The wall is over 1/4" thick and the fitting is tapered pipe threads for a tight fit.
  • 10/15/10 Installed intake manifold and rebuilt carburetor.
  • 10/30/10 painted the inside of the hood satin black. Worked on miscellaneous issues and wiring.

GOOD NEWS:

Mr. Elgin's son said the engine was overhauled in 1982 and sent me the below reciept, so it has 10,000 miles on it.
I removed the intake manifold and it is as clean as can be inside.

In a 1957 Hot Rod Magazine test a 57 Plymouth did 0 to 60mph in 9.6 seconds with the 301 Power-Pak engine.


I just installed the distributor with the new PerTronix electronic module.


The Carter WCFB four-barrel 385 CFM carburetor has been fully rebuilt and plated by
RECARBCO (www.recarbco.com) to original specifications.


Not having a location where I could install the temperature sending unit for a set of MOON gauges
I had a machine shop for $35 drill and tap a hole to install a fitting in the thermostat housing.
There is over a quarter inch of material in the casting to tap into.

NOVEMBER 2010

  • 11/3/10 Received and installed my distributor from PerTronix. They put in a new plate and mounted the electronic module. I installed a flame thrower coil to match the PerTronix system and give 20,000 more volts to the spark plugs.
  • 11/4/10 Fired up the Poly 301 - SWEET! Starts quickly, I had to fix some fuel leaks.

DECEMBER 2010

  • 12/20/10 Rebuilt Generator with new Armature (solved issue with high voltage)
  • 12/21/10 Install new regulator (voltage remains constant at 14 volts)

How to polarize a generator

To polarize a generator connect all wires to the regulator, connect the battery (negative ground) with the engine off.
Momentarily connect a jumper wire between ARMATURE terminal and the BATTERY (+) - a small spark should happen.
