Distributor ID

[Harvey W.]

I have a '67 L71. When I bought it, with the help of a knowledgeable NCRS member, we determined that based on the POP and the major parts that we examined that it was what we thought it was - a legit L71. I knew when I bought it that there were a number of parts that were not correct and after an extended sit in my garage, I got it back on the road about 2 years ago and am gradually replacing incorrect parts with correct parts for this car. Don't want to do a full restoration but want it to be as correct as I can as a nice driver.
One item was the distributor. I would like to sell the one that came out of the car but I am not sure what I have. I do not want to misrepresent it. The distributor that came out of the car has a part number on the collar - # 1111927. According to Colvin's Corvette by the Numbers this is for a '69 L88. As an aside many of the parts I am replacing are early C3 parts. However, the date on the collar makes no sense 2B22 which as best I can tell means it was made on February 22, 1972.
Can anyone help identify what I have here. I have lots of pictures and can send if that helps, just not sure how to attach them here.
Thanks in advance

Distributor GM #1111927 is, indeed, the unit originally used for 1969 L-88 and ZL-1. It was also SERVICE for 1967-68 L-88's. The one you have is a SERVICE distributor manufactured on the date you mention. This distributor was available in SERVICE for many years and was finally discontinued in October, 1977.

By the way, this distributor did not originally have vacuum advance and is a very poor choice for a street driven car. But, L-88's were never intended for street use.

Re: Distributor ID

Thank you Joe. I guessed that was the case, but found no reference that verified it. This has a vacuum pot - did the service items come with vacuum advance? It ran fine on my car - just wasn't correct. Thanks for your help.

The distributor had a "vacuum control" but it was non-functional as there was no vacuum nipple for vacuum to be applied. It could be that someone replaced it with a functional vacuum control, though. I didn't know that was possible for this distributor but it's possible it was.

Below is what the 1115373 "vacuum control" looked like. This was the vaccum control used on the 1111927.

Re: Distributor ID

Wow. 399.99. NOS.

If that's NOS, rhetorically.... why do the holes have evidence of screws? Hmmmm

Re: Distributor ID

It looks like it must have been modified. The guy that owned the car was a Chevy Dealer service person. Is there a way on this board to send pics. would to hear what you think. I may just have a Frankenstein piece.
At least it worked fine when I was driving with it.

I'm not 100% sure that this is an NOS piece, either, but it generally mimics the configuration of the original. I think it's possible it's some sort of reproduction. My recollection of the originals is that there was not a "tit" on the front but, rather, a hole with a tiny, crimped, internal flange the purpose of which I know not. However, it's possible this piece was made both ways. It was available in SERVICE until December, 1987.

The small hole showing in these two pictures on the back side of the tach drive bulge identifies the distributor housing as late 1970 and newer. That coincides with the 1972 date on the attached band. A closer image of the second photo in your post may show some numbers on the vacuum canister that might identify it, but it does appear that a variety of parts were used to modify this distributor. Properly done such modifications can make a well performing distributor.

Re: Distributor ID

Thanks Terry
It has been a mystery to me. NCRS provides such a great resource for solving questions like this for those of us wanting to learn more. I certainly appreciate those who take their time to help us all out. This had me stumped. As you suggested, I have looked closely in good light and find no numbers. But also, the previous owner worked as a service guy for a Chevy dealer. Looks like he did some backyard modifications to make it work in his car. It was just a used car when he got it. Why is still a mystery.
I have the correct distributor in my car now, but couldn't figure out what I replaced. Now I hope I can find someone who can put it to good use. At least I'll be able to provide an honest description.
