It my 1968 Corvette motor 327, Has a tube running a long side the distributor with a spring loaded cap. Is this something that should be maintained, e.g refill with oil or grease, when to stop refilling.

Also my carb does not have a vacuum unit? It has dual points

I'm been fumbling around w/these issues for a while now, taking what I'v read in my motors manual, the internet and you guys. I worked as an auto body repairman, so what I know about motor is just what I picked up here & there. Thimble size knowledge.

Any help Fella's with be greatly appreciate it.

Thanks Have a great weekend,

Steve

it may just be what used to be called an oil cup. Just put a few drops of oil in it. In this case a picture would be helpful.
What do you meen by a "vacuum unit". If you are talking about a a vacuum activated choke pull off it will help with cold starts. Again pictures would be helpful

Hello,

Thanks for taking the time. My Motors Manual referred to it as a Vacuum Unit, then the manual is 40 y/o. I attached a picture of the thing for you.

What is the "oil cup". Does it have anything to do with the tube that runs up along side the distributor? I'm not sure if I should oil it/grease it/or leave it.

Ayuh,... Yer picture is of a vacuum advance module...
It should have a vacuum line on it, to the carb, or manifold...

Nice pic, top bushing oil wick tube, fill'er up. No wonder we needed full service stations back when.

I believe that your distributor did not originally come in the 68 Vette.
I believe it to be a early model with only mechanical advance.

Some of the early Vette distributors are worth a good bit of money.

The pic I posted is a 55-56 Chev single point Delco (made by Prestolite) distributor (these dists were used in large trucks until 1961 according to GM). There was a later version 56-57 dist with dual points and a mech tach drive of similar design. The rest were Delco single or dual point dists with the advance weights above the points and below the rotor (some vette and trucks had mech tach drive also)

If I remember right very few 68 Vettes were 327s as the 350 was introduced in January 1969 with the early release of the 1969 Vette. The 1968 Vette 327s were large journal forged cranks, I believe and these are very rare as most 1968 327s and 307s were large journal cast cranks. So it is very possible that your Vette engine has been replaced with an earlier 327 especially if it has a sjc.

A different year distributor? Mmm, I wonder what year. Is it aftermarket or just a different year?

I'm getting depressed here, I want to drive my car!!

Take a pic of it and post it, there should be a Delco tag with a number on it riveted to the side.
By the way there is no vacuum advance on the one in the picture?

Does it look like this:



or this:

The first pic is it. Looks exactly like it. What year and modle did you say it came from (or did you ?

[topwrench]

He may be looking at a tachometer cable for a mechanical tach a lot of vettes of that vintage had mech. tachs

[cobalt327]

Distributor numbers for the '68 Vette- http://corvetteactioncenter.com/specs/c3/1968/68id.html Tach drive cable/cable connection is at a 90 degree angle to distributor body, the oiler curves up to be more or less parallel to the body and has a cap on it.

[Two8tyThree]

That is a 1956-57 Corvette (Chev/GMC truck 1956-61) dual point Distributor.
I believe the your dist number should be one of these:
1100891
1100872
1100879

This dist takes:
D-407 rotor
D-305 cap
D-103P points (2) dual
D-203 condenser

If you need parts or dist repairs, Bubba in Speedway, Indiana would be the guy to get them from. You can email him here:
