Duraspark distributor question

[260Alpine]

Earlier Duraspark used the smaller cap, Duraspark II had the larger cap.

Thanks Jim and Bill,

Bill, I agree that they don't shatter for no reason and perhaps Jim is correct that it shouldn't have been a roll
pin as it cant handle ( or at least the one the rebuilder used couldn't) the torque on the shaft. Maybe it should
have been a solid pin. I'll see if they have a good thick wall pin or at least something with a little interference
so it holds.

I'll let you know what I find.

Thanks again,
Steve

Well, I took the distributor to my machinist this morning. He's very experienced with distributors
and can spot problems that most can't. Besides the shattered pin, he found that the shaft is very worn
enough to cause a significant wobble on the reluctor. If fact that may well have done the pin in.

So, it's new distributor time. My next question is will a Duraspark II dizzy bolt in on an older engine.
This engine is a '75, the DII came about in '76.

Anyone know?

Thanks!
Steve

Yep.

Does the Duraspark II distributor require a different Module Box and Coil that the smaller diameter Distributor?

 

[260Alpine]

Duraspark II box. Coil is fine. I prefer the 4 pin GM HEI with newer low resistance HEI or TFI coil.

Thanks for the replies!

What color tab is on the Duraspark II module? I'm inclined to go w/GM
but we put a Duraspark harness in a little over a year ago, so don't know if the
owner wants to switch. We currently have the blue tab module.
Thanks!

Thanks Jim,
That's the same wiring and module that we've been using with the other dist.
Thanks a bunch!

I figured I'd follow up with how this all worked out. I was able to pick up a slightly used Duraspark II dizzy
from forum member Fergusonic ( Thanks Bradley!) When I got it, it seems that the only difference was the cap & rotor.
I changed out the breaker plate as the wires on the "new " dizzy were cut and the plug was missing. By the way, this
distributor has a roll pin holding the reluctor.

Once I retimed the engine ( it had been over a week since I removed the old dizzy and memory isn't as good as it
used to be!) the engine ran better than it ever had previously. I think Jim was correct, we had gotten a bad rebuild.
Upon closer inspection the old dizzy had one spring that actually did nothing. It was totally loose and provided no
tension.

Anyway to sum it up, the car runs really well ! If you get a rebuilt dizzy check it over very carefully.

Cheers!
