Default Vacuum advance

The vacuum advance in my '58 is not going to work. The return spring has way too much pull, so in effect it is disabled. My breaker plate moves easily with the vacuum advance taken off.

The replacement advances I've found all have the off-center arm. My '58 has a straight arm for the vacuum advance.

Should I just get a rebuilt distributor that has everything upgraded? Sources, suggestions?

Hey James,
I was fiddling with mine and broke one of the screw bosses off my distributor. I went to O'Rielies auto parts and had them get me a new one. I marked the way rotor button was, took old one out, put new one in and changed out guts. Button everything down got in Christine and she fired right up. Had to take timing light and fine tune.

The answer depends on a couple things:

* how fast do you want it up and running properly

* how original you want to keep it

* how you want it to perform.

I found the timing was flaky on mine and that lead me to finding the bushing in the distributor was worn out. I walked into the auto parts store and had a replacement within a few hours. Maybe $60 ?? So that was the quick fix.

You can send yours out and have it rebuilt. In the process you can have it "curved" to get near optimum performance. This will take longer and cost more. They decide when it should be firing at full advance and then put weights and springs in that accomplish this.

You can get a junker and steal parts from it for yours. I would want to make sure the diaphram was working properly and had no holes in it, not to mention the bushings (does it have much side to side play?)

Thanks for the suggestions. Oreily's is not able to look anything up directly for a pre-1962 car. Are all the 352 distributors the same, i.e. a '63 Galaxie? Are other FE engines the same, like 390 or a 360 truck?

Hey James,
The 352, 390, 406 and 427 are the same blocks! (I think that is correct, I know the 352 and the 390 are the same) You are correct O'Rielies book and computers only go back to 1962. Have someone there call the main company, they will cross reference it for you. Mine was for a 1962 390!

I've got a '62 Fairlane 390 distributor ordered from OReily's. We'll see how it compares when it comes in tomorrow. Thanks for suggestions everyone!

I think I'm going to have two options. Get the rebuilt one now to get going quickly and keep the old one to be rebuilt possibly at some time later.

Hi Astrowing, I'm not sure you've got the right one coming. To the best of my knowledge 1962 was the first year of the compact Fairlane, which never had a 390 - its V8 was a windsor small block. I'd hate for the wrong one to turn up, it might pay to double check?

You are probably right if it is for a Fairlane. Most of them were 260's or 289's. I did see the 390 on the order form though, so who knows what I'll get.

It was for a 390 and the correct one. Got it installed this evening and working. I believe I'm getting better combustion so the timing is more accurate than the original distributor. I don't think anything had ever been done to it. We're talking original over 50 years old!

I was also working on the brakes this evening so didn't get a chance to really play with the timing because I had to move it over one tooth to get the vaccum advance away from the fuel pump lines. Once I get the timing light out and set it all up, I think it will be much better.

Is everyone using vacuum advance from the base of the cabuerator, which was the factory way to do it? Or the other option is to use full manifold vacuum?
