Date Codes on 1967 Engine Accessories

[Rick R.]

Should date codes on small block carburetors, starters, alternators, distributors, etc be prior to the engine assembly state stamped on the block pad, or closer to to the official build date for the car? If the latter, how close? I believe ( but don't know this) that the engines would have been shipped from Flint to St. Louis as long blocks and these parts would have been installed from stock at St. Louis.
I'm contemplating spending the money to replace a non original carburetor and starter. What would be the most authentic date codes to specify on these parts considering an engine assembly date of January 25, and an official GM car production date of April 17? I'm thinking towards the latter part of March or first week of April. Thanks,

Rick R.

The answer is yes, at least no closer than 2 weeks before engine build date. Most of the time it was 2-8 weeks before engine build date. It may also depend on the option.

All components of the engine as shipped from the engine plants should be dated on or prior to the engine assembly date stamped on the engine pad. Usually, these components will be dated within a month of engine assembly but it can exceed that in some cases. Within 6 months prior is NCRS accepted. All engine peripheral components which were installed at St. Louis should be dated prior to the car's build date. Usually, this would be within a month, or so, prior to the car's build date but there are exceptions for certain components that often exceed this time frame. However, NCRS and other judging organizations allow up to 6 months. You can easily determine which components were installed at St. Louis by referring to the AIM. If a component is shown with a part number, it was installed at St. Louis.

So, what were the actual dates of each component originally installed on your car? The ONLY way to know that is to have the known, original component installed on the car. How do you know that if you're not the original owner of the car? There's no way.

Very helpful. I just reviewed the NCRS 1967 67 TIM/Judging Guide and it spells out the alternator date should be prior to the car's build date, and mine is dated April 5th, so probably good there. As for the carburetor and starter, what is the AIM?? Duh.

AIM= Assembly Information Manual. These are copies of the original document used by St. Louis to build the car and are specific to each year model. They're available at modest cost from the NCRS Store as well as most other Corvette parts vendors.

Thanks Joe, I'll get one.

Re: Date Codes on 1967 Engine Accessories

So this old thread is bad info? A 721 carb recommended as perfect for a mid February CAR build date? I'm about to spend $1,000.

Rick,

I believe the carb was installed in STL, so it's date should precede the car's build date, not the engine build date.

I think that's true. Trusting Joe Lucia's post regarding the AIM as being the definitive source for which components were installed at St. Louis, I'll get that book and go from there. All posts appreciated.

k,
By all means get the AIM. You will be surprised at what information it holds, but it does require a learning curve to understand it.

I'll give you some Cliff notes.
Distributor was on the engine as shipped to St Louis. The other items you mention: Carburetor, starter & alternator were all installed from stock at St Louis. Further these items were built in batches so some dates are common and others are not so much.

Terry, Thanks for your succinct reply that goes right to the heart of my question.

A couple of photos of engines ready for shipment to assy plants (no carbs etc.)... and the engine trim line Prior to installation.

The third photo shows transmissions installed on the engine. I am not aware that any transmissions were installed at the engine plants. I think that picture may be from an assembly plant.

Re: Date Codes on 1967 Engine Accessories

Terry, That is what I said "engine trim line prior to installation". I guess I assumed that people knew where the engine was installed in the car.......
The engine trim line was when all the appropriate accessories were installed on the engine.... such as carb, ignition wiring and shields, starter etc.
Sorry for the confusion.....

I read your caption too fast. Now that I look at it I see the ... representing the engines traveling to the assembly plants. Sorry I missed that the first time around.
