Distributor replacement options

[Invectivus]

I have a C6 200 from a 66 mustang in my 67, so just the load-o-matic stuff, and my Vacuum canister is shot (i get no advance on RPM changes). The dizzy original to my 67 was torn apart and rusted out so it's not much of an option.

I have a DS2 out of an 81 fairmont which looks ok (little dirty is all) and the rest of the stuff for a swap but i'm torn. I don't know for sure if it's good, not sure if shops even test them anymore but that's an option if they do. I'm leery of putting it in without a recurve, but i'm also leery of recurving before i get my head/carb changes decided on and completed as i'd just need to recurve again.

Will the stock curve (or the curve with the spring swap from the falcon handbook) handle things ok in the interm?

Yes I think it will work fine until you decide on all your mods. At that time than you can optimize the tune by having it curved.

The stock DSII from a '82 Zephyr works great in my '66. When I change head/cam/exhaust I'll have it re-curved to optimize my mods. I have a non SCV Cali 1100 carburetor.

Howdy Vec:

You've got good advice from Bubba and Jim. If the shaft does not have excessive play and the module is good go for it. You will love the difference. Recurving the mechanical advance with the spring swap is a good step and many have gone no farther regardless of other performance upgrades. The point is to get max advance in sooner. I've used the DS II swap with no recurve and with recurved, on both stock and modified engines and I can't say that I noticed much difference in my daily drivers. The big difference is going from Points to DS II. I currently have a recurved DS II in my modified 250 with an MSD coil and will likely never have anything else. (Did I say "never"?)

The only remaining question is what carb are you using? If it is still the 1100, does it have a SCV or not? If SCV, Plug it and either use no vacuum advance with 12 - 15 degrees of initial, or tap a manifold vacuum source for the vacuum advance and use 6 - 8 degrees of initial, and assess from there. If it is a non-SCV 1100 just use the ported vacuum source and try 10 - 12 degrees of initial advance with a stock 9:1 CR head and stock OEM cam and assess from there.

Keep us posted.

Adios, David

Bench testing the distributor module is rather easy with a ohmeter. Between orange and purple you should read 400-800 ohms. Between either and black, above 70K ohms.

That is good info to have from Explorer about testing modules. I am running a DSII from about an 81 Fairmont I think got the distributor, coil, wires and blue strain relief module from picnpul and it works great. I don't miss points at all so far. Should be a good improvement on a stock motor.
