1967 1111194 auto cam

[Timothy B.]

Can someone tell me the correct autocam # for the 1111194 300hp distributor for 1967.

Thanks as always, Tim

Tim -- per the Oct '67 P&A30 catalog, the shaft with autocam (ie. the football welded on the top end) is part # 1968080 ('67 base engine, manual & auto.).

But I've got a suspicion that you're asking for the stamped number(s) on the football, for which I have no idea .

The stamped code of the auto cam atop the 1968080 shaft is "165".

Thanks Wayne and Joe , that's exactly what I am looking for.

Tim,

Not sure about the numbers, but the photos below are my original 67 base engine distributor, disassembled for the first time:





Not sure if there were any numbers on the cams, but there were on the base after I pulled the shaft, whatever it's worth:



The vacuum can was replated.

Typical overhaul after the tach drive gear on the shaft gets bunged up. Replaced the shaft, cleaned things up and it works fine.

Cheers,

Thanks Jerry,

Did you have to replace the main shaft because of tach gear damage?

Tim,

Correctomondo! Both the tach gear and gear on the shaft were bunged up.

Not sure if you can see the damage to the shaft here:



But the housing was badly worn by the old gear, which offset it to the gear on the shaft, and then bunged up both. Here's the wear on the housing:



See the worn spot, it looks like the top of the old cross gear which is probably a long ago replacement (on the left):



I was able to fit one of those nylon buttons in the worn depression without drilling the housing. With the new bronze tipped gear (on the right) it works fine now.

Jerry,

Where did you get the new mainshaft and how does the car run compared to before if you remember.

Jerry,

I don't remember off hand, but it was either Paragon or Corvette Central, my main vendors. More likely Paragon as they give a 10% discount to NCRS members.

Once I got the correct orientation of the dimple to the drive gear, and the timing adjusted to the original 6d spec, the car ran like new, and better than the replacement distributor which had been on the car for a number of years. I really don't remember any appreciable difference in the replacement shaft vs the old.

Other than the shaft, crossgear, points and condenser, I put back all the original parts cleaned up a bit, in the original positions and orientations.
That's why I take pictures before.

I did also get a bushing kit, but I didn't have to use it.

The "machine work" which the cross gear performs on the thrust surface of the housing is the exact reason that the vast majority of these gears (and the main shaft gears) fail. GM's addition of just the cheap, little nylon button solved this problem completely. Brass buttons or brass-ended cross gears are probably better but the nylon button works fine. I put 150,000 miles on one and it never failed.

Re: 1967 1111194 auto cam

I remember when first looking at this gear damage in the housing I thought it was supposed to be there.

Tim,

If you are going to do an overhaul, get one of those nylon buttons, cut the little mounting ears off, and you will find that it fits just great over the wear mark in the housing.

I put mine in with just some grease, but it would be better to glue or epoxy it to the housing, so you don't have to hassle with it to replace the gear on the car.

I got my nylon button from Bair's, get a couple.

I believe these nylon buttons are those also used on the distrib. weight plate (points bump) or TI (star wheel). IIRC they replaced the permanent metal slide "buttons" around 1969.

Re: 1967 1111194 auto cam

Jerry,

I was wondering how the autocam on the new shaft compared to the original. Years ago I bought a main shaft from a company called Street products, I believe in PA. and remember the person I spoke with asked me if I wanted a performance or stock (low horse) part.

Naturally I opted for the HP part and the 67 engine ran very good. Since then, I purchased a original 1111194 from a 68 300hp car and have mined the main shaft to restore my 67 part. This 1968 distributor has very little use and there is not even a groove in the housing from the tach gear thrust.

Have you tried the new restored holley on the car yet? Mine is running beautiful, I hate the fact cold weather is upon us in MD.

Tim,

Here's a photo from the Corvette Central website showing the difference in the HP and standard shaft top plate:



Mine looks like the lower one.

On the Carb, I'll probably put it on this spring, just in time for the story to come out. Thanks for your help on it. I used your method of planing the main body and base plate.
