63 Chrysler 300 Prestolite Distributor Parts

The Prestolite (was called "Auto-Lite" in those days) distributor changed *very* little from the mid '50s through the late '60s in terms of physical construction detail, so physical interchangeability on this vacuum pot is large. On many of the distributor vacuum advance pot's cap can be removed by unscrewing it, and the spring and spacer changed to alter the calibration of the unit. A few of these units show up on Ebay: Item 2478121108 (if this exact one won't work for you, it looks like the guy has many more) Item 7902094108 DS |

In order to avoid massive pinging on the street, you have to retard the base (initial) timing so far that starting and fuel economy go right out the window. And you can't swap out the springs from your old distributor, since the Prestolite springs and weights are different from the ones in the Chrysler-built distributor. There are ways around this -- you can swap in the springs from a Chrysler-built single-point big-block street distributor, or engage the services of one of the relatively few places around that can and will still dial-in a distributor on a Sun machine -- but why? Chrysler's points/condenser ignitions work just fine. I doubt you're using this 413 '63 Chrysler as a daily driver, and even if you are, the points last a long time. Far less effort just to replace the vacuum pot, or even to go through the distributor and replace its bushings *and* the vacuum pot. (This also keeps things looking original, which is always nice to see even if you don't care about car shows where judges lower their noses from the air long enough only to subtract points) DS |

The 63 300 is somewhat of a daily driver, as far as I am trying to get it as reliable as possible so that I feel comfortable in letting my wife drive in the summer, which was the main purpose of purchasing the car in the first place. There are many many non-originals on this car that I'm trying to slowly put back, and fortunately the distributor is original and for now would like to keep it that way. I have no grand illusions about entering into national shows as the car needs some work, but I do like to show her in non-judging categories at local events, simply because there were only 1800 made, and while you see a hundred cameros, chevelles and firebirds at most shows, I've yet to see one 50's or 60's 300, even at mopar shows where barracudas, dusters, chargers, and roadrunners abound. PS...I agree about the judging. I've attended a few, and overheard some of their comments whilst judging cars. |

I've got a 64 300, but not the letter car, and the only time I've seen another one was in a junk yard a few years ago! I started out with the, "I have no grand illusions..." saying also. Didn't take long to just blow off that statement! That was 3 years ago and it's still not finished. Thought it might be completed by July or August but ran into another time delay thing. Legendary Interiors is backed up 12 weeks with interior work, so the car should be done except for the interior. Maybe I'll try driving while sitting on a milk crate! =8^0 SCARY thought!!! |

Use quality points (I prefer NAPA's premium Echlin points, *NON*-ventillated if given the choice, which does exist for many of the '60s-'70s Mopar applications) and a good condenser and you won't have reliability problems. > am trying to get it as reliable as possible so that I feel comfortable > in letting my wife drive in the summer One of the best ways to increase the starting and driveability behavior of Chrysler products of the day: Remove the metal fuel line that runs between the fuel pump and the carburetor. Install a Dorman 492-024 or Everbrass 1791 fitting in the output of the fuel pump and another in the input of the carburetor. Install a length of 5/16" ID *fuel injection* hose (stamped 30R9, don't use old-fashioned 30R7 hose) between the two fittings, routing it vertically from the fuel pump, well clear of the exhaust manifold of course, across the RH rocker cover and directly to the carburetor fitting. Then locate the *metal* (not plastic, please) fuel filter between 2 and 9 inches (or so) above the fuel filter in this new line, oriented vertically. It's best if you can arrange it so the fuel filter is behind the alternator (cooling air current moves heat away from the fuel filter). Secure all hose ends with proper fuel injection hose clamps (rolled edges, etc. so as not to cut the hose). This modification greatly reduces heat transfer to the fuel upon "hot soak" (engine shut down at operating temperature, underhood temps soar), and substantially reduces hard hot starting, stalling at idle and next-morning cold starting trouble.

I rerouted a few weeks ago as you suggested, because the original route carried it resting atop the rocker cover and down the front of the exhaust manifold. I did mount the fuel filter vertically, however, I used what was in there which was the plastic filter with replaceable cartridges. I know that's not stock so I had planned to replace anyway with the metal type, but for my edification, other than not being original, how is the metal filter superior? Thanks for all the great help Robert |

More predictably resistant to all the different additives and alcohols and ethers that find their way into modern gasoline. DS |

I know a couple of guys running the Pertronix unit, and they really like it. Fits in a stock distributor, gives electronic ignition stability and reliability. But the distributor has to be in good MECHANICAL shape (bushings, mech. advance, and vacuum advance) in order to use it.

It might be easiest to go down to NAPA, plunk down for a rebuilt common-as-dirt single-point distributor (ask for one for a '67 to '69 New Yorker with a 440) and then put the Pertronix unit on that. With the Pertronix, there is no benefit to dual points anyway. Put the rarer, more valuable Prestolite dual point on a shelf until you can send it off and have it carefully restored. |
