I would appreciate knowing the GM number for that unit or its service replacement.

1111194 is original number, I do not believethere is a service unit available.

Thanks Fellows. It has PG so I guess it is 1111117. BTW what would be the difference between a 4-speed and PG distributor? I am looking to purchase a solid shell and rebuild it. I would want to get the correct parts.

Paul-you can use almost any cast iron distributor with tach drive from this erea. The banding and differences just relate to the autocam on top of the mainshaft, the springs and weights, and the vacuum can installed. The bands can be purchased with the correct number and date if you are after that for judging. What is more important is that you have the unit recurved for your engine's cam and setup....Craig

Thanks Craig. I thought the body itself was pretty universal. And in my search on the internet I noted the number is simply a band rather than a stamping. As to recurving I have a bit of a dilemma as I do not know what cam is in the engine. From its mild manners and no lope it is most likely a typical 327/300 version. But I suppose a good shop could get matters close. In this city of ~1M people I believe there is only one shop left that can do a distributor recurve! At least that is what my friends at a GM dealer tell me....

Paul - if you search the archives here, Duke Williams has had excellent posts on vacuum can choice (VC 1810 I believe is good for your probable config), as well as some basic initial settings and full centrifugal advance settings as rough rpm ranges. This should get you into the right range very quickly...Craig

Forgot to mention, the VC1810 choice is from NAPA......Craig

Might be worth mentioning that there are also reproductions of the Vacuum Advance can available with characteristecs pretty close to the originals.

Re: GM Number for a 1967 327/300 Distributor

Thanks Bill. One colleague suggested that NAPA VC1765 might be more appropriate than VC1810 for the 327/300 with Powerglide. Any thoughts on that?

Re: GM Number for a 1967 327/300 Distributor

To properly select a vacuum can you must know the idle vacuum with about 25 degrees of total idle advance. If your current vacuum can is in the ballpark it should be providing full vacuum advance at idle. If not, you need to select a different can - one that provides full advancee at least 2" BELOW what the engine engine idles at, so if you state your idle RPM and vacuum and total idle timing, I can give you a specific recomendation based on a objective criteria. Also state what the stamped numbers are on your existing can, so if can be identified.

Thanks Duke. I guess this thread comes to a full stop at this point as my 1967 is in secure winter storage until April. So I cannot give you those specs. But thanks for getting back to me. It was my intention to do a complete rebuild of an old distrib during the winter months in the basement. I will probably press ahead with that with the fine tuning to be done in April. I should have asked the question in August!

The OEM Vacuum can for a 1111117 is a 1115355 vac can. The specs on the can are start @ 5-7 inches, 8 degrees (dist or 16 crank) all in at 11.2-12.7 inches of vacuum. Why not see if you can find one in Reproduction if you are restoring the car? ( Info per Delco Remy "Test Specifications" 1964-67 supplement.

Bill,
I will check with GM on that number on Monday. But usually I run up against "discontinued." I am a former GM employee and the parts fellows dig a little deeper than for most people but after 36 years there is only so much out there.

Try Corvette Central or one of the other reproduction houses Paragon and CC both carry them, although I have not checked that exact part number. Be Carefull of spo, as they are packaging generic parts in AC-Delco boxes these days and you won't get what you really need. GM Parts is becoming worse every day as a source for parts useful in a restoration. I worked for them too, in the pre-Delphi spinoff days.
