Part number help - calling Joe Lucia

[Nick Vigorito]

The distributor I have in my 67 Corvette (327/350) has a band that says it is an 1111196 distributor and the date code is April 10, 1965. What is the application for this distributor for a 65 Corvette? Is it perhaps for a 65 327/350?

Thanks!

According the the NCRS Spec. Guide that is the correct distributor number for a '67 L-79 without K-66, and it is also unique to the '67 L-79!

1965 327/350 lists distributor part no. 1111087, with the following specs.:

Cent Advance:--------- 0 @ 750......15 @ 1500.......30 @ 5100
Vac Advance:---------- 0 @ 4in-hg.........16.5 @ 8.2 in-hg

So is there any way to ID a distributor other than the ID tag? I have looked mine over and can see nothing. Thanks!

Re: Part number help - calling Joe Lucia

The numbers stamped on the vacuum can and weights give a clue. Also, if you characterize the advance curve and it matches the specs of the part number on the tag, then it is probably what it purports to be.

It's very difficult to do without the tag. The distributor part number represented a configuration made up from a certain combination of components. For a Corvette tach drive distributor, these components consisted of the auto cam (brazed to the top of the main shaft), the vacuum control, the centrifugal advance weights, and the centrifugal advance springs. It may be possible to ID the vacuum control and the auto cam is SOMETIMES identified by a stamped-in 3 digit ID code (for which we don't have a decoding table). However, it's virtually impossible to ID the weights and, especially, the springs. Without being able to positively ID ALL of the components, there's no way to positively ID the distributor part number.

Addendum

By the way, there are basically TWO ways to create any distributor part number. The first is to obtain KNOWN examples of all of the parts I previously mentioned which were used in a particular distributor part number and assemble these parts into a complete distributor. This is EXACTLY how the folks in Anderson, IN created a particular distributor in the first place. Of course, to do this you pretty much have to have NOS, "in-the-package" examples of all of the parts which were used for any particular distributor part number. That's not so easy since most of the parts were GM-discontinued years ago and are not reproduced in their exact, original configuration by anyone.

The second way to do it is to take a distributor of ANY original part number and have it custom-curved to match the SPECIFICATIONS of the original distributor. Using this method, non-original parts or original parts can be modified or "mixed-and-matched" to create the same distributor advance specifications as an original distributor part number. You might say that using this method, a distributor which is the duplicate of an original part number is created by "reverse engineering". Although the internal parts may differ from the original distributor, the end product is functionally identical.

The can has 236 16 stamped on it. Can't see anything on the weights top or bottom but I did not pull them to look at the underside of the mount point. I don't think that says much. Wasn't that can was used on lots of different distributors
